Of course. I'm sure there are other things in various new kernel that
older user space isn't aware of. It just depends on how far back you
wish to go.

But it won't really be broken. I actually tested compression patches on
F-14. All you need to do is pass resume argument to grub for 2.6.37
kernel you installed by hand (and at present, you can only do this by
hand). If Fedora folks decide to upgrade the kernel to 2.6.37 for F-14
(they already have for F-15, so they must be aware of the issue), I'm
sure they'll fix util-linux-ng, dracut and whatever else is required for
this to work.

PS. Koji build of the kernel for F-15, based in 2.6.37-rc5:
