Add another one to the spontaneous reboots for 3.0-STABLE

Machine (512Mb dual Xeon/400) was fresh installed with 3.0-RELEASE,
cvsup to RELENG_3 as of 1900 CST 02/09/1999.  Everything went fine
during the build, with no problems encountered, but since rebooting
into 3.0-STABLE, I'm experiencing effectively random crashes.

However, I can reproduce the problem completely by launching
enlightenment/gnome as my window manager.

Backtrace looks a little screwy, even when I install the debug-full
kernel without saving/stripping it..  machine has 512Mb of RAM and
a 768Mb swap partition.

System board is a Supermicro P6DGH with MPP level set to 1.1 in the
BIOS - setting it to 1.4 prevents the machine from booting at all.

Suggestions?
