1. I'll start with your kernel question:
$ rpmquery kernel-PAE
2. So F-13 was updated from 2.6.33 series to 2.6.34 series kernels.
Many of the updates related to Radeon, since a lot of work
was done on this architecture during last year
$ rpmquery --changelog kernel-PAE | grep -i radeon | wc -l
BTW: this is just from June-2010. If you'll check on F-12, you'll find a
similar count from Mar-2009 to this July

3. As a Fedora user myself, I must say you may have chose the
wrong distribution for your criteria.
Fedora is fast paced distribution:
* Major release every 6 months
* Only two supported releases (n, n-1) -- your F-12 should be EOL
this January (no more bug fixes, no more security updates)
* Many packages are updated during the ~1 year of a release
(including the kernel)
4. If you want long maintenance cycle the "best" options now are:
* Wait few months for Debian-Sqeeze (real soon now)
* Wait few months for Centos-6 (REHL-6 are in Beta now)

5. You are welcome to join us, Fedorans , with a 6-12 upgrade cycle.
Things (mostly) work, and because of the fast updates, there are
cases where you get fixes quicker -- (e.g: Radeon)
Not to mention I like to develop with modern tools (gcc, autotools,
Oops, almost forgot. If you still want to compile your kernel. You may want
to start with current Fedora kernel as a basis:
yum install rpmdevtools # For the next utility
rpmdev-setuptree # set up a empty packaging tree under ~/rpmbuild
# Let's download + expand the tree
yumdownloader --source kernel
rpm -ivh kernel-.....src.rpm
rpmbuild -bp kernel.spec # This is just the *prepare* build step
# You'll see two obvious directories: vanilla-2.6.x* and linux-2.6.3*
If you want to see how many patches separate the vanilla from Fedora:
grep '^Patch[0-9]' ~rpmbuild/SPECS/kernel.spec | wc -l
It should be only 100-150 patches. If it looks bad to you, reconsider.
Distibutions that you wanted (3-5 years between major upgrades) have
around 1K patches :-O

If it's there and you can see it, it's REAL
If it's there and you can't see it, it's TRANSPARENT
If it's not there and you can see it, it's VIRTUAL
If it's not there and you can't see it, it's GONE!
