I'm using gekernel.

Maybe, I did not (yet?) try dracut.

Not with mine :)  Maybe I'll give dracut a try. It seems to be a nice
utility, and I was about to try it, but then I read about Dale's problems
and decided to stay with genkernel for a while.

Which I do, every partition (including /) is on LVM, and except
for /usr, /usr/src and portage stuff, all is encrypted. But maybe it's
time to drop some partitions, and maybe include at least /usr and /tmp in
the root partition. /usr would be encrypted again then, but the overhead
seems to be small, so why not.
