Well, that's already what I do and intended to do (and that's clear from
the beginning of the bug report).

Wrt not introducing subtle security problems, what I mostly do is remove
the security backports from the grsec patch which are already applied to
Debian kernel, so this part is fairly straightforward.

Now indeed when doing the job for Squeeze kernel it's a bit less
straightforward because of the huge amount of driver backports, but from
my own experience, the conflicts are still mostly about changed context
lines.
