Hmm, maybe nowadays disabling AGP DMA for the K8M800 is not 
necessary, as it doesn't seem to cause lockups any more.  But if 
such a risk of lockups is there, I think the right to do is to 
switch the option off by default.  Better have a slow system that 
works, than one that suddenly locks up after an upgrade.

Andrey, could you please test with which kernel version this 
lockup/artifact problem first appeared?  If possible, it would be 
nice if you could use git and git-bisect to find the exact commit 
that is to blame.
