Yes i am in the same boat as you with a rev 0.
I took my Cybergraphix drivers as far as i could and just swapped the voodoo driver file to one i knew worked.
Open pci is excluded from us rev 0 users.
The big joke is/was the offer of fixing/upgrading them to a rev that worked. Yeh that was only likely to happen if you
lived next door to DCE and handed them in personally.
