I know the existing code when it was back in the freebios codebase and PCI only handled this correctly, so it should be just a matter of a little bit of debugging to get this to happen automatically if it does not already. > > I think the best to use VGA is > > 1.

I wonder if there are driver issues when you put the 8151 on something besides bus 0. > We have tried everything to forward VGAIO behind 8111 and 8151 > bridges but fail. Do you know anything about it ? That is very weird. Besides the card not working what test are you using to be certain you have failed? Are you failing to read/write an I/O register. It occurs to me LinuxBIOS might be different enough in pci layout to confuse the option ROM on your card. Plus I think there are some special bits of AGP initialization that we might not be doing.
