FYI,
While it is slightly off-topic of the (I agree, real)
technical issue here, note that polling is not "normal" on ACPI systems.
[1] was on SuSE Linux 10.0, which on their own decided to
over-ride the kernel and enable thermal zone polling by default.
This turned out to be a bad idea because it exposed BIOS bugs
in ACPI thermal zones that were never exposed on other operating
systems - evidently because the other operating systems never
poll thermal zones, they are entirely event driven.
cheers,
