Just in case this happens to kilbo or anyone else.
I had to go here:
http://forum.tegratab.com/viewtopic.php?f=6&t=16
put this on a microSD (and change the recovery\command text file so that "SDCARD" says "SDCARD2" like it says)
After that I had to do a Factory Restore / Wipe Data. Then rebooted, but it hung up again. I powered down, then did the power + volume+ again and it brought me to the main boot screen.
Data was all wiped, but at least it's not a brick.
