AFAIK, there are a couple of similar bugs out there. First this one for AGP cards which is fixed by running PCI mode instead. Then there's a bug for PCI cards which obviously have no choice of mode (bug #114520). If that same bug also affects some AGP cards, I don't know. Some people only see issues after resume from hibernation or sleep.

There used to be a bug when the AGP speed in BIOS mismatched the one in the driver, but the driver has now been fixed to use the BIOS one by default (bug #67487).

There could be a mother bug that causes all of these issues, but it's likely they have different origins and must be taken care of one by one. It can be in the card driver, the mesa libraries or the kernel drm modules.
