I believe part of my problem is that (my) toolchain needs to match that with what CM was built with. (Which means I would probably have to build the whole CM package in order for it to work). I have an overclocked recovery, but that doesn't make much sense :)

There seems to be lots of discussion between conflicts between smartreflex and various governors.

Since these things normally run at 396 or 800 Mhz, I wonder if it would be more advantageous to tweak ram settings and such at those speeds

TBH, my main goal is to get Arch linux on this thing.

To that end, I plan on purchasing a Prolific PL2303 USB to serial adaptor so as to have a console.

This won't help me with any bootloader work, but I don't wish to disassemble my nook to solder in two wires to get a uart console (would still have to purchase a FT232RL USB to Serial breakout board for voltage level shifting).
