yes, and it will hopefully also fix the r100 crash.

Yes, it worked for a while. I tried only from a live cd but I was able to
browse the web which usually crashes very fast when the setting is incorrect.

None I am aware of. The settings in the AGP section of the bios do not change
the value and do not enable changing it.

fwiw there is a report of Radeon 7200 crashing at >1x and Radeon 9600 crashing
at 8x in the referenced launchpad bug. But there are no details.

Generally if changing the bios setting makes a difference we are probably
missing something because the gart driver should be able to change the mode as
well.

It may be even that the bios is defective and does not set up the card properly
for 8x, and the gart driver does not do it either.

Unfortunately I probably do not have access to enough hardware (and enough
time) to find out which part is broken. Either of
board/chipset/bios/card/driver can be sub-spec or broken, or some combination.
