Comment 1 for bug 150693

This is the diff from 2.6.22-13-rt (stock) to my "kind of working" version. There are lots of changes, but I guess the only ones that may be relevant are the ones in the IDE section (the other potentially relevant changes in the list of partition types handled didn't change anything in practice - I tried that first because I thought it might be caused by my LDM partitions).
