I didn't respond because I couldn't give a "definite answer".
There are no definite answers with vgas.

Oh alright I'll try.

A good range of Nvidia cards right up to Geforce 4s may work,
or can be made to work by altering vgadb, or tweaking code.

You will need to check the archives, as there are several
semi-independent efforts at improving support.

The fundamental problems are

1. acceleration may or may not work
2. depths > 8 may not work
3. snow may appear on the screen
4. laptop screens using Geforce Gos won't work

This is all down to a partial but incomplete port of the Xfree86 4
driver. It is believed that a complete port will make the vast majority
of cards work. In particular, there is some "memory access
optimisation" code in there which is missing from the Plan 9 version,
and could easily account for most of these problems (except 4).

As I say, check the archives. There has been a lot of traffic on the
subject.

As a summary, you have a good chance of getting most cards to work
acceptably in 8 bit depth, except laptops.

There you are; definitive, if not really definite.

It depends on your boot floppy's file, called vgadb.

The part of nvidia card of mine is as follows:

ctlr
	0xC00A2="NVIDIA TNT2 Model 64 BIOS V2.05.13 "	# NVIDIA TNT Model 64
	0xC0108="AOpen MX200 VGA BIOS Version 1.00-143N"	# AOpen MX200 Geforce2
	0xC0108="NVIDIA GeForce2 MX-200 VGA BIOS"	# Prographics GeForce2 MX-200
	0xC00CB="ASUS AGP-V7100 VGA BIOS Version 3.11.00.04" # ASUS GeForce2MX
	0xC0074="NV"			# GeForce 3
	link=vga
	ctlr=nvidia linear=1
	hwgc=nvidiahwgc


You can edit that file before booting the system by some editer on Unix or
windows.

Hi

I am upgrading my PC and since i don't want to 'miss' plan9, exactly which
nvidia cards are supported?

The hardware requirements page says there is good support only for savage4
an riva TNT2. Also in the same page there is a note that GeForce in not
supported but in this list some report that it worked fine on GeForce2 MX.

Can someone give a definite answer?

Thanks
