Check strace, %preun, %post, %postun, and other related trigger operations and post your results where the bottlenecks are. Could be rpm, could be db, could be scriptlets .. who knows.
It's neither of these. According to top, all the CPU was being charged to the rpm process alone. The kernel package's %preun consists of:
/sbin/modprobe loop 2> /dev/null > /dev/null || : [ -x /sbin/new-kernel-pkg ] && /sbin/new-kernel-pkg --rminitrd --rmmoddep --remove 2.6.10-1.12_FC2
Which is nothing.
rpm was eating CPU like there's no tomorrow. strace was showing lots of read/writes, likely its database.
