Well, 2.6.35 is also a long term version. Maintaining all the long term
versions is a lot of work (it takes time to simply validate a patch for
every new release). So, we probably can not maintain support for all the
long term versions, we would probably have to pick one.

Since the I-pipe patch for ARM skips even versions (in order to reduce
the time spent issuing I-pipe patches), and since it is more recent, I
would rather go for 2.6.35.
