Ingo (Molnar[*]) is curious about whether this is solved in the S7
voluntary preemption patch... so I put an even more experimental than
usual version of the kernel in the Planet Edge repository, it'd be
interesting to see what happens with this one in your setup if you have
the time:

apt-get install kernel#

Hmmm, it could depend also on which kernel options are enabled in the
build, maybe I'm missing something important. Could you send me (off the
list) the .config file used to build the kernel in Gentoo?
