Ollie,

Should only forward to 8151 only. For the AGP is on 8151.

The under normal bios, you need to use the most update kernel or may be 2.4.
22 to see the 8151.

YhLu,

We found that under normal bios, the AMD8151 is not present. Is there 
any bits to hide it ?

We have tried everything to forward VGAIO behind 8111 and 8151
bridges but fail. Do you know anything about it ?

It's probably sitting on a peer bus? Maybe it needs an entry in the pirq
table, like bus one did? (just guessing)

it's weirder than that. The AGP video card is visible but the bridge to it 
(8151) is not. So the card works, is accessible, but the bridge is 
invisible (in normal bios).

this is 2.4.23. The 8151 is totally invisible, under normal bios, and 
totally visible, under linuxbios. Some trick in the hardware?

We used the same 2.4.23 kernel under normal and linuxbios. The 8151 is
not present with lspci when booted with normal bios.

What exactly is the peer bus stuff?
