As for my memory leak problem, I did finally track it down to the kernel-preemption patch... my best guess is that it interacts poorly with some of our platform-specific modifications... though what I can't figure out is why even with preemption disabled (in menuconfig), I still have the problem. I'm looking through the patch again to try to find additions that aren't #ifdef'd out when it's disabled, but I have a feeling that since I've found a way to fix the problem, I'll be moving on to other things soon. Anyway, thanks to everyone who offered advice, and if any kernel preemption experts want to set me straight, feel free!
