Problems with startx on 5.2-RELEASE

Hi, -

there have been reports about X11 freezing the entire system on 5.2.

I managed to get rid of these freezes by removing SMP and apic support 
from my kernel. (Single CPU machine, of course.)

Although I suggested this procedure to some people on freebsd-questions, 
nobody seemed to take notice of it; everyone solely blamed ACPI.

So I guess that the following confirmation may be of some interest for 
those that don't have time to follow freebsd-questions.

Greetings and thanks for your great work,
- Martin

The same problems with X on 5.2-RELEASE as in RC2 (X
freezes on startup or shutdown).

hint.acpi.0.disabled="1" helps, but causes strange warnings
in dmesg (and shutdown doesn't switch power off...).
Then I've commented out SMP and apic from kernel, as
Martin suggested above and problem disappeared, acpi works
