It's enabled, but diasbling it didn't seem to make a difference either.
FWIW, http://penguinppc.org/~daenzer/config-2.6.5-rc2-ben0-ck1 is my
current, preempt-less config.
Note that I'm not sure how tightly the problems are tied to swap; after
they start, they seem to persist even when swap is no longer used. It's
just the best criterion I've been able to identify so far.
