I get this accross the board on my test system too. All clean downloads.

A quick look at the combo-patch and the broken-out patch seems to
indicate they are not in sync with each other. In the combo-patch we
have this hunk (which is the one which fails):

In the broken-out directory the only patch which references this file
has the following different hunk:

Looking at 2.6.19-rc6 this second version seems completely reasonable.
The former does not.
