Comment (by wmb at firmworks.com):

 Here are some debugging techniques:

 1) After a "Page Fault", you can get a post-mortem call stack trace with

   ok ftrace

 2) You can use the OFW debugger to step through the execution of olpc.fth
 as follows:

 a) Edit olpc.fth, replacing the last line (which contains "update-
 activate-and-boot" with

       debugging update-activate-and-boot

 b) Power cycle the XO and hold down the X game key to ensure that OFW
 boots in interactive mode.

 c) If you typed the ESC key to get to the ok prompt, type "boot"

 d) When the debugger fires up, you can step forward with "space", go down
 into procedures with "d", and back up to the caller with "u".  By doing
 that, you can find where the problem is occurring.
