It's a Toshiba Satellite L25-S1192.  The chipset is ATI Radeon Xpress
200M (RS480).

Verbose dmesgs are up at http://www.gank.org/freebsd/l25

acpi+apic.txt is a 6.0-RELEASE GENERIC kernel (before I upgraded the
memory, but the APIC thing is independent of that)

apic2.txt is a verbose dmesg with my current kernel (stock 6.0-STABLE +
read-after-write change to local_apic.c).
