after updating a current i386 system which uses the aperture driver
(pkgsrc/sysutils/aperture) using todays sources, the kernel dropped
into ddb during boot (AFAICT while /etc/rc.d/lkm3 called modload):

xf86.o: uvm_fault(0xcb43c540, 0, 0, 1) -> 0xe
kernel: page fault trap, code=0

(copied manually, typos possible...)

After rebuilding the aperture driver modload succeeded to load the

The "old" kernel had the same version number as the new one (2.99.10)
and was built using sources from 2004-10-18; the "old" aperture module
was built using sources from 2004-10-24.

Should I send-pr?
