Here: http://www.rockbox.org/twiki/bin/view/Main/DocsIndex#For_Developersis everything you need. It takes a little while to read and to setup everything, but then you can always build the newest version and you are independent.

As far as I can see, the OF also only switches the backlight off. The D2's screen is hard to read without backlight, but still possible under the right light conditions.
Do you really think it drains that much battery?

The LCD itself probably isn't that much - the backlight will be a much more significant battery drain. Still, on some other players (eg. iPod Video) a nice boost in battery lifetime has been gained by switching off the LCD when not in use. Although if we power off the LCD, it does take some time to power on again, so the "user experience" might not be ideal...
On a related note, I recently had Rockbox playing music constantly for over 24 hours, so our battery usage at the moment isn't exactly terrible. I'm not really too concerned about power consumption at the moment - I think the D2 port has rather bigger issues to worry about than that. :(
ps. I haven't mentioned it here yet, but the "user timer" has now been implemented, so things like the Metronome plugin and Doom should now work properly.
luck3r:
The OF only turns off the LCD 30 seconds (or so) after the backlight was switched off, but stops updating the screen, as far as I can see.
Edit: I can confirm that Doom works now, although the sound quality is low and the MIDI music doesn't play yet. Radio is also working fine.
Something else: The delay until Rockbox turns off the device is too long. The device would automatically shutdown after a few seconds if the power switch was held for >1s AFAIK. Maybe this can be prevented by the firmware?

Hi
Is it just me or is the current version of the bootlader broken ?
I bricked my D2 three times (on OF 2.59 and 3.57) trying to get the latest svn version...
It usually works well compiling and patching ...
Thanks

Well, the revision 20603 works.
Did you run the configure tool?
Running make you get the message that your version is old and you should run configure, is it that case?
