This is a known problem, and fixed in 2.2.8 and later. The keyboard
controller on Dell's motherboard is not as compatible as it should be.
Please apply the attached patch to /sys/i386/isa/psm.c and rebuild the
kernel.

No need to switch to the serial mouse. The patch should work.
# I think I sent out this patch to quite a few people on the FreeBSD
# mailing lists. Which mailing list archive did you search?
