Unfortunately, this patch will not apply to my src tree for 2.6.35-rc3,
even after I fixed the unwanted line wrap in the first active line.
I get:
[root@coyote linux-2.6.35-rc3]# patch -p1 <../2.6.35-rc3-test.patch
patching file net/core/skbuff.c
Hunk #1 FAILED at 532.
1 out of 1 hunk FAILED -- saving rejects to file net/core/skbuff.c.rej
Did my grabbing it with swiftfox damage it even further?

That line 532 is not at line 532 in my src tree, its at line 516 here.
I have seen this sort of thing before when using bz2 src files, but this is
all from gzipped stuffs. ???
Thanks for any hints.
