I have a similar problem with a Supermicro dual XEON workstation and Fedora Core
4.0.  The UP kernel works fine.  The SMP kernel boots but the keyboard and mouse
(both PS/2) don't work.  I have tried with ACPI both on and off in the BIOS and
with passing ACPI=off to the kernel.

Same problem here with the two most recent SMP kernels, 
kernel-smp-2.6.12-1.1456_FC4 and kernel-smp-2.6.13-1.1526_FC4. 
Moderboard is Iwill DPL-533.

Non-SMP kernel works fine.
