Can I run a 2.4 Kernel on FC3

FC3 takes more advantage of 2.6 (than FC2 did): as John thought, udev
and hotplug rely on the /sys work that was done during 2.5 development.
(And that work was largely responsible for the change in ABI that means
the original device driver won't work in 2.6)...

You probably could get something working with a static /dev and manually
configuring stuff that FC3 normally leaves to hotplug. But it wouldn't
be a standard FC3, and you'd have to be very careful while upgrading.

Hint: on the fedora-devel or fedora-test list recently, it was pointed
out that
chattr +i $filename
will stop practically *anything* upgrading that file!
