This seems reasonable - I've used the SGML &device; for removable media
boots on things such as USB sticks or CD's on some setups before.
commiting - 

I'll test on a few other setups.  I know some IBM machines have a
firmware limitation with &device; length - limiting it to 256 bytes
which I hit when using it multiple times in a CHRP script (to auto
detect if 64-bit or not and execute a different conf).  I think we may
want to possibly not use the entities on CHRP and just expand the device
for now.  Could you supply an updated patch?

I'm unsure if you let me know what hardware/firmware you've tested on
that'd be useful.

At this stage ofpath is really somewhat buggy and something I'd like to
eventually get rid of, possibly in favour of using ofpathname from
powerpc-utils, but that wont be for 1.3.14.
