That sounds like even more reason to break it out into a separate patch.

Actually, I really think that you sould either provide a set or smaller
patches, or incremental patches. Its quite hard to follow what is
changing with the current jumbo-patch format.

Its also quite unclear what if any portions you would like merged, and
even which tree you want them merged into - you patches are against 
2.6.18-rc5, but the ia64 tree seems the most likely path, and your code
doesn't apply there because some of the changes are already present.
