There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:
<darktama> it's not worth limiting the quirk to just where we know it can
work? i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC
<curro> and with that quirk there's no way to tell if the load comes from
the VGA or DVI port

On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.
This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets. The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.

We just need to clear the SBA and ENABLE bits to reset the AGP
controller: If the AGP bridge was configured to use "fast writes",
clearing the FW bit would break the subsequent MMIO writes and
eventually end with a lockup.
Note that all the BIOSes I've seen do the same as we did (it works for
them because they don't use MMIO), OTOH the blob leaves FW untouched.

We totally fail at detecting un-POSTed chipsets prior to G80. This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.
NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

All indications seem to be that the version 0x30 table should be handled
the same way as 0x40 (as used on G80), at least for the parts that we

actually trying to achieve, and unifies the 0x30/0x40 parsing.

The connector table index in the DCB entry for each output type is an
index into the connector table, and does *not* necessarily match up
with what was previously called "index" in the connector table entries
themselves.
Not real sure what that index is exactly, renamed to "index2" as we
still use it to prevent creating multiple TV connectors.

It appears we aren't required to do memory sizing ourselves on nv40
either. NV40 init tables read a strap from PEXTDEV_BOOT_0 into a
CRTC register, and then later use that value to select a memory

earlier cards) with INIT_IO_RESTRICT_PROG.

Apparently the original reason for checking this was there were known
register accesses that caused hangs on some chipsets. This was more
than likely because of incorrect parsing of previous opcodes, and I
hardly think aborting a script half way through is going to be any
better (in fact, we have had bug reports where this has been the cause
of s/r failures among other things).
This patch (which has been in Fedora 12 for a long time now) removes
all checking for known register ranges, and just leaves the check to
ensure the access is within the mapped aperture to avoid an oops.

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.
This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.
This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
