... you mean at this point that OpenFirmware doesn't read the
/boot/olpc.fth on your SD card, right?  You've tried changing it to emit
test characters or something?

boot from the NAND flash, right?

I've reviewed your script.  The first line does not contain the key text
that DebXO uses:

	\ OLPC boot script

The second last line uses unfreeze instead of dcon-unfreeze.

There's some strange thing done to change the loading of the initrd,
using constants that aren't defined, so I don't know what that code you
have is trying to do.

However, I've checked, and the code between the [if] and [then] does not
trigger on Q2E41b.

My guess is that you haven't tracked the changes in OpenFirmware
correctly, or that the wrong first line text is used, or the unfreeze
should be dcon-unfreeze.

Lastly, check the line containing "root=UUID=4C67-D0F1", as it appears
to have wrapped in your e-mail.
