*jumps up and down like a hyperactive two-year-old* LAB can do that stuff!
I would definately like to see LAB used on more than just ARM.

If you can have it in the kernel you can have it in LAB. LAB's command line
API is really easy - I've ported userland apps (mtderase) to LAB in sub-10
As to size issues, we're at a 512k zImage. We do not have bzImages on ARM, so
I could not tell you the size with it. 512k is with a few ARM-specific
drivers, and jffs2. It does not have networking. This is with kernel 2.6.

Oh and did I say LAB had MTD support? :)
