I tried this a few times, and it never worked very well.
First I ran it via the bootloader included with mb_vanilla. It acted the 
same as the kernel I built, freezing just after "portmap &" possibly 
when it tried to run a mkdir command.

Second time I ran it by typing in "con 0x80000000" in xmd. It came back 
with some memory related errors (can't allocate memory for 3 or 4 
commands like cat) but it did bring up a shell prompt. I typed in "ls" 
and it froze.

Third try I plugged in a live ethernet cable before typing con 
0x800000000. It didn't bring up a shell and looked like it was caught in 
an infinite loop in the eth0 driver. I've attatched the bootlog from 
this attempt. It also had memory problems like "Unable to read 
code+data+bss."

With a crossover cable connected to my PC, I got output similar to try 
2. That output is also attatched...

I'm going to try this on some different boards when I get time later 
today or tomorrow.

Cheers,

Aaron
