Summary: Old AGP vid card went bad, replaced with the ATI Radeon 4600 AGP.
Updated ATI drivers and mobo drivers.
Set AGP to 8x in ATI Catalyst, reboot, sets itself back to nada.
Set BIOS to auto-detect AGP speed, nope. Set BIOS to 8x AGP, reboot, nope.
No errors detected in DXDIAG.
Odd thing is that since installing the new AGP card, my CPU Usage stays in the 70% to 80% range AT IDLE. It seems like the mobo and vidcard are fighting each each other.....
