I managed to work nVidia 7600GS (10de/0392) card for Plan 9.
As I don't know to whom I send this patch, and it's very small,
I decided to post it here.
/sys/src/cmd/aux/vga/nvidia.c should be changed as follows:
===========from here===========

< case 0x0390:
---
> case 0x0390: /* nvidia 7600 */

---
> nv->pramin[0x0818] = 0x0100805F; /*WaitVSync not
> possible, if possible =0x01008062 */

< nv->pgraph[0x0608/4] |= 0x00100000;

> nv->pfb[(0x0608/4)] | 0x00100000; /* K.Okamoto */

< } else {
< nv->pgraph[0x09F0/4] =
nv->pfb[0x0200/4];

nv->pfb[0x0204/4];

PS. nVidia 7950 card should work, too.
