My bad.  The series I sent was incomplete and did not inclde the patch
69ec87efa8 (ACPICA: Add subsystem option to force copy of DSDT to
local memory, 2010-04-01), which is in squeeze (see bug#596709) but
not in the unpatched upstream kernel.

If you would like to test the patches against an upstream kernel
(which seems sensible enough), here are instructions:

1. apt-get install build-essential git-core

2. Fetch the 2.6.32.y longterm series:

     git clone -o stable \
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git \
	linux
     cd linux
 
   Or, if you already have a clone of linux-2.6.git:

     cd ~/src/linux
     git remote add -f stable \
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git

3. Grab Debian's patches, too (to save the effort of a trivial
   conflict-resolution in backporting one of the patches).

     git remote add -f debian \
	git://git.debian.org/kernel/linux-2.6.git

4. Check out stable-2.6.32.y:

     git checkout stable/linux-2.6.32.y

5. Apply patches:

     # ACPICA: Add detection of corrupted/replaced DSDT
     git cherry-pick -x 729df0f848da

     # ACPICA: Add subsystem option to force copy of DSDT to local memory
     # This one has a trivial conflict with another change.  So you
     # can use the upstream commit and fix it up by hand:
     git cherry-pick -x 69ec87efa815
     # Or re-use Ben's conflict resolution:
     git reset --merge
     git cherry-pick -x d65cf0ba0563

     # ACPICA: Update DSDT copy/detection
     git cherry-pick -x 43323cb4c4b6
     # ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT
     git cherry-pick -x aa2110cb1a75
     # ACPI: fix early DSDT dmi check warnings on ia64
     git cherry-pick -x cce4f632db20
     # ACPI: invoke DSDT corruption workaround on all Toshiba Satellite
     git cherry-pick -x 100cf87788c0

6. Build:

     cp /boot/config-$(uname -r) .config
     make localmodconfig; # minimal configuration
     make deb-pkg

7. Test:

     dpkg -i ../<name of package>
     reboot

8. Report back on results, and kick me if it doesn't result in the
patches being passed on to stable@vger.kernel.org.

Thanks again, and sorry for the fuss.
