I bought a VisionTek branded NVidia GeForce2 MX 400 video card and followed
the instructions at http://users.bigpond.net.au/nwaples/install.txt as per
the Wiki and previous posts.  The controller isn't in vgadb and a
"distinguishing text string" doesn't exactly jump out at me from the
attached vgainfo.txt.  Ideas?

I could trade this card in (yet again) for a TNT2 based card and try that,
as it appears to have better Plan9 support, although being a PCI card (vs.
the AGP one above) I'm not sure what the performance implications would be.
