Ah.. I misunderstood you.  When you said "device" I thought you were 
referring a to an OFW device tree device, like the device that lets you 
do MSR access.  I didn't realize you were talking about access to the 
boot partition.  I could help you with a firmware issue but I'm afraid I 
can't help much with 12.1.0.

The boot partition is supposed to be accessible via /bootpart/boot or 
/boot if its not then its just a bug that will get fixed up later. 
12.1.0 is still in its infancy.  I wouldn't expect much to work for quit 
a few more builds.

Like Martin's e-mail suggested you can open 'olpc.fth' in a small editor 
under OFW.  You can edit the file there and make your changes.  No Linux 
involved.  Although I'm not sure if that version of firmware can edit 
files on the bootpart correctly.  There have recently been a bunch of 
fixes for OFW  ext2/3/4 support.

Alternatively you could decompress the os image file on a desktop 
machine, edit the file and then re-compress it.
