Rebuilding FC3 base kernel from source

[Philip Prindeville <philipp_subx redfish-solutions com>]

What do I need to do to install the FC3 kernel sources and
build exactly the same kernel that comes with this distribution?

Somehow my install got hosed, and when my system boots I
get a lot of messages that insmod can load /lib/dm*.ko (at least
that's what I think it was).

Sigh.

Thanks,
