That's an interesting question.  I did some searching and apparently a
number of other OEMs are all having issues with this even under
windows.

If I had to guess, I'd suspect that Intel has pushed similar checking
of ACPI into the windows driver.

Can we just get this terrible code ripped out until the OEMs get their
act together?  This is really bad user experience.
