[ltp] T61 system board (42w7872)

[Paul Seelig]

Both the FRU 42W7648 and 42W7872 mainboards come with integrated Intel 
graphics and don't suffer from any sich heat related issues. The nVIDIA 
based mainboard variants of the T61 which were produced before 08/2008 
typically die like flies because of bad soldering material used by 
nVIDIA for the production of the graphic chips.
