I have rebased these onto the top of the 2.6.27-10.20 and pushed those
up for any intrested testers.  So far we have three positive tests
results from the boot crashing Samsung laptops, with some reports of
improved brightness handling from them.  That seems pretty positive.
Will see if anyone from the primary report gives us any feedback this
weekend.
