Testbios works for ATI too !!!

[Li-Ta Lo]

Hello,

I just tried my "imporved" testbios on ATI 9800PRO
under LinuxBIOS. It can init the card. The only problem
is that the normal BIOS store the PCIDEVFN at some bytes
in the C segment so I have to change the vbios.bin a
little bit.

I will commit the current testbios into V2 tree after
doing some clean up.
