the 8111 is the pci connection. register 3e.b in 8111 is set to 0xf, which should pass vga i/o to the pci bus.
the vga card, using Ollie's 'userio' program, does not respond to byte accesses to 0x3cc or 0x3d4. Under normal bios, all these register settings are the same and ... the card responds.
It seems you've solved this now, according to the later success report. Excellent news indeed! :)
I would've suggested a modified POST card or logic analyzer to see if the writes made it to the bus. This is somewhat more of a LAN approach to diagnostics, but might have helped anyway. LAN bridges also tend to just make packets disappear mysteriously.
What was the problem, anyway?
