Failing to initialize an S3Virge PCI board

[Ruben F. <par...@gm...>]

Hi,

I've tried multiseat X, using the new modular X.org 7.0. When booting 
the pc with 'Init display first : PCI' in the BIOS, everything works 
fine. I have to probe the NVidia GF2 card without -isolateDevice first, 
but afterwards, everything works.
When using 'Init display first: AGP' however, the VBios of the Virge 
card isn't loaded, OR the wrong VBIOS is detected. I've tried with and 
without isolateDevice. This is the logfile:
