Most of tests are done with SMP kernel without APIC_IO.

UP kernel doesn't make any difference. SMP/APIC_IO kernel panics 100%
somewhere in USB detecting (haven't debugged it closer yet). I have tried
already all common stuff ;).

with these, but it will not give me any practical benefit, I'm afraid.
