Marc,

if more / other information is needed let me know.
I'll try to go through the points as described in
/usr/src/linux/REPORTING-BUGS:

[1.] Bug reported on system startup.

[2.] no obvious problem detected besides this message
besides apic errors on both CPUs.

[3.] kernel BUG at buffer.c:827! - invalid operand: 0000 - CPU: 0

[4.] Linux version 2.4.0-test11 (root@nmb) (gcc version 2.95.2 19991024
(release)) #1 SMP

[5.] output on system startup:

[9.] there is nothing unusual besides KDE2.1 crashes more often than KDE2.0 .
This may have other reason ;o).
