[Lucid-lbm] SRU: Make thinkpad-acpi work with lbm-alsa

[Stefan Bader]

SRU justification:

Impact: As we were "asked" to go ahead and get a very recent thinkpad-acpi
driver enabled in Lucid, which exports an alsa mixer for the hw mixer that only
exists for ThinkPads. we now have a problem when people with TPs are asked to
try the latest ALSA from LBM. After installing LBM-alsa the thinkpad-acpi module
refuses to load as it wants the other symbol versions from the kernel.

Fix: I don't know of any better way than to put the thinkpad-acpi driver as it
is in Lucid into LBM and build it against the LBM-alsa core. It is then thrown
into the alsa package which mixes things a bit but I did not want to create a
new package for that.

Testcase: Verified that after installing lbm-alsa before caused thinkpad-acpi
not to be loaded. With the new version this works (and at least the wireless
card in that machine also still works with lbm-wireless installed.
