Well, since X is a userland process, I wouldn't expect it to be able to
crash the kernel, even if it plays with /dev/agpgart in a bad way. It
can even be a security issue.

Yes, I've seen those reports. That's why I holded on backporting the driver
from testing/sid to my etch system.

Do you know if Linux had improvements in this area from 2.6.18 to 2.6.22 ?
