Side note - I've tested them on the EeePC that had trouble resuming due to 
interrupt timings, and it suspends and resumes fine with these patches 
(modulo some new X problems, but that's what I get for living with 
Fedora-11 testing).

Of course, it also suspends and resumes without them, since the CPU "cli" 
was sufficient for that machine, and it doesn't have any ACPI issues. But 
it's still an ack that at least nothing breaks that I can tell.
