These terms have nothing to do with linux, they're ACPI things from
within the BIOS. the GPE is a General Purpose Event I believe. The
_L00 event seems to be an event which is generated if the machine gets
too hot - It may be called something different on a different
manufacturer's BIOS.
What you need to do is run an ACPI enabled kernel and dump the
/proc/acpi/dsdt to a file (cat /proc/acpi/dsdt > mydsdt.aml). You can't
read this directly as it is in a compiled form. You need to disassemble
it and you do that with the iasl assembler/disassembler you can get from
Intel's instantly available technology pages.
(http://www.intel.com/technology/iapc/acpi/downloads.htm)
Once you have it disassembled, try "compiling" it straight away and you
will probably find that there are errors and warnings. Check the acpi
mailing list archives for details on how to fix these.
Once you have it working, compile it into the kernel - how to do this is
covered in the archives as well. Booting with this kernel should make
your acpi work much better. If it doesn't solve your heating problem
then if you put your disassembled and original dsdt on the web somewhere
and post a message asking for help, with links to these files on the
acpi list then you are likely to get some good assistance.
It is definitely worthwhile, my laptop now runs about 99% of the time
with no fan - showing it's much cooler.

Good luck.
