Subject: [GIT PATCH] ACPI patches for 2.6.25-rc2
Hi Linus,
please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release
Fixes a pair of a boot regressions, and some churn mostly related
to some of the new thermal and thinkpad code that went into -rc1.
This will update the files shown below.
thanks!
-Len
ps. individual patches are available on linux-acpi@...r.kernel.org
and a consolidated plain patch is available here:

ACPI: TSC breaks atkbd suspend
TSC is used even on machines when CONFIG_X86_TSC is not set (X86_TSC
means _require_ TSC), but it is not properly disabled when it is
unusable, because ACPI code understood the config switch as "may use
TSC".
This actually fixes suspend problems on my x60.

ACPI: thinkpad-acpi: add tablet-mode reporting
A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the
existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the
X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is
tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is
set).
Add an attribute to report this information, "hotkey_tablet_mode". This
attribute has poll()/select() support, and can be used along with EV_SW
SW_TABLET_MODE to hook userspace to tablet events.

ACPI: thinkpad-acpi: make the video output feature optional
The video output port control feature is not very useful on many ThinkPads
(especially when a X server is running), and lately userspace is getting
better and better at it, so it makes sense to allow users to stripe out the
thinkpad-acpi video feature from their kernels and save at least 2KB.
