Keep the FC6 kernel at 2.6.20 or move it to 2.6.21?

There is another 2.6.20-stable release in the works and I think we should
release that for FC5/FC6. The work is already done.

In the meantime I've started collecting fixes for 2.6.21 and I think it will
be at least decent after a 40-patch or so update (not just a small two
patch update like 2.6.21.1.)
