Looks sane, but I'd prefer one ioctl for both, with a parameter indicating which operation is to be carried out. I'll prepare a patch when I'm finished with the ACPI thermal/fan suspend (seems to be broken to me now, please follow the bugzilla entry at: http://bugzilla.kernel.org/show_bug.cgi?id=7122).
