Yup.

1) It's GPL'd and I prefer the the more open GMGPL'd FSF version.
2) I've been reliably informed that the FSF has more fixes/features
than that version of the GPL'd version.
3) Some of the files from the bare board support has already filtered
down into the FSF tree.
4) I'm not rewriting anything, I'm using the files that already exist
within the FSF tree.
5) You do need HW specific code as well, this works alongside the RTS,
even AdaCore don't provide that for ARM, they do provide what you need
for NXT OS development though.

Luke.
