Does not work for AVR32 devices, AVR32 AP700X only supports booting from
NOR flash. Will be changed in future devices though.

Seems sane, depends on your application. I guess GUI with tons of
graphics?

I have heard one report on 2 GB NAND device being slow to mount, but
that may be kernel JFFS2 related and/or extreme slow once when writing
cleanmarkers problem.

Others report 1 GB being fast and nifty.

PS! I only work with AVR32 products, so I have little knowledge about
the ARM line. I guess Ulf can fill in the missing spots.
