thanks for the acpidump.
It shows lots of dependencies on "OSYS", which is set differently for Linux.
The dependencies show up in places like battery, AC, wakup support and docking.
Basically, it sets the DSDT to run in "unknown OS" mode, since there
is not a single test for OSYS = the value set for Linux.
I will blacklist OSI(Linux) on this box (which for 2.6.23 and later
is no change, since OSI(Linux) is off by default. If we find incompatibilities
with how Windows exercises the box, we'll fix those -- which is a better
course than running the DSDT in "other" mode that the vendor surely
has never tested.
