Anyone rolling a kernel nowadays?

I do this on my Gentoo system, where it's very little extra work because you
have
to compile the kernel anyway.  It shouldn't be a lot under Ubuntu either,
except
for the actual compilation.  Almost always, I just copy the .config file
from the
previous kernel and do "make oldconfig" to bring it up to date.  Then
compile
and install as normal.

In my case it's much less a matter of modules (I still have a few) than
tailoring the
optimization to my Xeon processors.
