Thank you for being so understanding. Also for releasing the stable patches.

The last patch I tried was for 2.6.22-rc7 and it wouldn't boot. Older 
patches could boot but if I shuffled some files around and tried to 
execute something out of a layered branch, it'd oops.

So I just built 2.6.22.1-u1 for an initramfs booter using squahsfs 3.2 + 
tmpfs, booting up our standard image (currently in production via 
unionfs 1.x), and it works great!

Booted, let me run stuff. No complaints!

I'm going to let it run for a few days, but this is fantastic for us, 
thanks again!
