* NV20
* -----
* There are 3 families :
* NV20 is 0x10de:0x020*
* NV25/28 is 0x10de:0x025* / 0x10de:0x028*
* NV2A is 0x10de:0x02A0
*
* NV30
* -----
* There are 3 families :
* NV30/31 is 0x10de:0x030* / 0x10de:0x031*
* NV34 is 0x10de:0x032*
* NV35/36 is 0x10de:0x033* / 0x10de:0x034*
*
* Not seen in the wild, no dumps (probably NV35) :
