have you tried pci-sig(a)znyx.com ? It has people who works on designing
PCI buses as their day to day job.
I think you send email to pci-sig-request(a)znyx.com with subject

Bitworks needs help.
We currently Intel Celeron 440bx design that has ATI M1 video chips on
board. Off and on for the past 6 months or so I've been working to make
them work under Linuxbios, ADLO, or testbios, etc.
I've have finally managed to show that the problem is hardware related
to our design. As I can make a PCI eval card from ATI work on a Asus
P2B motherboard and linuxbios using X to softboot the card. The same
setup on our board fails to work.
Somehow the SDRAM inside the M1 chip is failing to initialize properly.
The video output has all the right VSYNC and HSYNC for the 800x600
mode I setup but a black screen and a large square block for the cursor.
If I exit X and try to write/read a value into video ram I get garbage
back. This works on the Ausu P2B.
Things with our customer have gone critical. I've got to have something
working by the end of October.
So I'm in search of people who really understand PCI and video stuff and
are available for consulting either on site here or I can come to thier
Also any one have on know of place I can go to get a PCI complience test
done? Or hardware I can rent? We reciently borrowed a HP 16500B logic
analyzer with a Future+Systems passive PCI hookup but it dosn't do
complience testing. We need an additional card for that.
