for PCI and AGP cards you can scan through the bus and fetch all vendor:device numbers of type 7 (vga compatible) IIRC and then match them against a database. i have the code for this if you're interested. for ISA cards that has PnP functionality you can get the vendor string using a PnP interrupt service routine, I have never actually done that but i know that it is possible. But for most cards you can use the VESA VBE API to fetch the information, you will have to do this from real/virtual mode afaik. If you're not interrested in programming hardware you can use the pci interface in /proc instead which is the best solution if you're running linux. ;o)
