--- Comment #11 from Robert Hancock <hancockrwd at gmail.com> ---
Most likely in 2X mode some of the data transfers to/from the card are getting
corrupted somehow, causing the GPU to not respond as expected and causing the
lockup detection.

I believe that for AGP problems on VIA chipsets, some people had luck with
playing with the "AGP Driving Value" setting in the BIOS, if you have such an
option you can try using different settings for this. (As I recall, most AGP
chipsets would handle this setting automatically but the crappy VIA AGP
implementation used a BIOS setting which sometimes required the user to enter a
different value in the hope it would get the card to work properly.)
