I feel relieved to hear that somehow ;) I saw a similar problem on
some of PCs around, but disable_on_poweroff always worked. Does updating
BIOS fix it?

I recommend against compiling acpi driver in the kernel.

I believe I know it. In short, don't use that option, and build acpi
driver with an environment variable ACPI_DEBUG set to yes:
export CFLAGS='-O -pipe -DSMP=1' (only for SMP kernel)
make obj && make depend && make && make install
The problem is that you used an option which only applies to acpi driver
compiled in the kernel, but if you build the kernel by buildkernel or
nativekernel, that option gets propagated to module build without adding
necessary files. When you reboot your laptop, acpi driver fails to
load because of missing symbols which are supposed to be defined in those
missing files. If this is the case, /var/run/dmesg.boot should contain
