panic from July 21 kernel (acpi related?)

Hi,
I upgraded my kernel recently:
FreeBSD fark.com 5.2-CURRENT FreeBSD 5.2-CURRENT #2: Wed
Jul 21 17:17:10 PDT 2004 root at fark.com:/usr/obj/usr/src/sys/fark i386
Unfortunately it seems like a problem from April is still with me.
It's really weird; when I boot my laptop with a MS USB keyboard and a
logitech usb mouse (and external monitor hooked into the back) on wall
power, this crash never happens. But I got the crash below on wall power,
without the mouse. It seems like loading without acpi gives better luck,
but I've had it crash without acpi also. Seems like folk-lore evidence;
so maybe there's some factor I'm missing.
Not using the custom DSDT.aml didn't change anything. My system is a dell
d800 with bios rev a9.
Please let me know if I can provide more info.

can't-read-my-own-writing stuff :) )
