There is some ACPI support during kernel compile, and I think it might
require some setup in some other file to activate it (I'm not positive
where). I have heard of it causing problems too, so it might not be a
full implementation and it might work well on only some machines. You
can probably find more info in the kernel source directory
/usr/src/linux/Documentation/. Try this from there:
rgrep -r ACPI *

Items like this are also typically required to be enabled in RH in
/etc/sysctl.conf, but I'm not sure about this one.
