Yes, it should be possible. In fact, it should be still there if you
have not erased it... You have to install the yum-allowdowngrade plugin
and then explicitly tell yum which kernel version you want to install,
yum install kernel-rt-2.6.29.x-yyyy --allow-downgrade

Hmmm, from what I can ggogle it would seem it is some sort of problem
with ext3 vs. ext4. I _think_ the default install in fc11 is ext4
instead of ext3.
Sorry, I don't know exactly what might be happening...
