Looking at the DSDT link posted, those variables are never set in it. I wonder
who, or what, is expected to set them then...
Perhaps it would be worth experimenting instead with OSI when booting and see
what happens then? e.g.
acpi_osi="!Windows 2006"
(Perhaps OSYS also triggers an SMI trap which does or doesn't do it? Worth a
shot at least).

I've also had a report from a user the other day that hit the same bug on an
Aspire 5710 series (which seems to have the same root cause, from glancing
over the DSDT):

Acer BIOS's never expose the fan, AFAIK (and it's not available through WMI
either).
