I had the same problem until today. If ACPI was enabled, I would get a
panic on boot. I removed MAXMEM from my kernel conf, recompiled, and
voila, no panic. ACPI looks like its working, according to the dmesg,
where any attempt to load it before panicked with pmap_mapdev: Couldn't
alloc kernel virtual memory.
Is there any reason, on newer motherboards, to need the MAXMEM option?
Without it specified, I see all 256M in the system. I originally had it
specified for the old K6-2 MB I had in this system. The new MB with a
Duron onboard doesn't need it.
Just my $0.02
