So preempt yes, SMP no.

And there is quite interesting (for me) part of dmesg :

00000030000000 (ACPI NVS)
767MB LOWMEM available.
found SMP MP-table at 000ff780

I had the same problem (if it is problem :-) also with 2.4
I don't know if it is problem because "everything" works fine, but maybe it 
will help you(me :-).    David
