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).
