        I briefly looked into this awhile back.  The firmware is a rather 
odd embedded RTOS beast:

6Softune REALOS/FR is Realtime OS for FR Family, based on micro-ITRON 
COPYRIGHT(C) FUJITSU 
LIMITED 1994-1999

... can be found within the firmware binary.  I'm not real saavy on 
hacking at that level, but it'd probalby be pretty ugly to do.  The D300 
has a larger userbase and thus larger hacker userbase.  They were also 
doing fairly simple things... just enabling features that were basically 
already there.  The hack we're talking about would be quite a bit to code 
up in a reverse-engineered way.
