I used dpkg -i to install it, sources are here:
http://people.debian.org/~dannf/tmp/
To create an unpacked source tree, you can:
dget http://people.debian.org/~dannf/tmp/linux-2.6_2.6.31~rc6-1~experimental.1~snapshot.14160.dsc
cd linux-2.6-2.6.31~rc6
./debian/rules setup
It is a pretty vanilla 2.6.31-rc6.

I don't see any obvious fixes between 2.6.31-rc6 & 2.6.31 - is the fix in kyle's tree?

Yes, it does. (echo t > /proc/sysrq-trigger didn't though, for whatever reason).
