You should check sysctl hw.acpi.thermal and look at the temperature value.
If after sitting there for a while, it looks like it's close to _CRT
(critical), then don't do that.  However, most of the time it should be
fine.

One of the things on my list is to add enough validity checks to
acpi_thermal that we can re-enable automatic shutdown -p when the box
hits _CRT.

That should just disable the one component that is giving you trouble,
leaving the rest of acpi available.
