Sure thing, that would do it, but it is hard to report bugs
and system crashes without a proper debug kernel.

But it seems to run now quite stable while using the debug kernel
with the freebsd agp architecture, so i'll stick to that for the time
being... The messages don't seem to have any effect on the system
stability.
