Hi gumpo, your in luck, i`ve been looking into getting one of these cards for my system and have been looking on the net for reviews etc and have come across this problem already
I believe the fix is to download the AGP specific drivers from the manufacturers website directly and not use the ATi CCC and drivers
E.g. If you have a Sapphire card go to the Sapphire website or if you have the HIS card go to the HIS site
Theses cards do seem to be suffering from poor driver issues
Sapphire Technology - drivers
Sorry cant provide link for HIS as the site appears to be down at the mo
D
Edit: As for the graphical errors you get during gaming with the drivers that do work, from what I have read, (depending on what
CPU you have) the
Cpu can cause a bottleneck in the system if it is not powerful enough to keep up with the
GFX card
