Oh... I had a laptop that had some ACPI issues... I ended up having to update my BIOS to fix the issues, though I could work around it by running acpi=off (which is a terrible option to have to use) and I eventually found running the 64bit version (even though I only had 2 Gig of memory) work remarkably well to address it.
There may be some ACPI options to fix your issue... but that can be a pain in some cases... I had to do a Kernel bisection to try and figure out where the problem started. No fun.
