I have just updated the Rockbox 2.5.1 download for Archos machines to include the following:
Rapid exit from the Menus is provided by holding the F1 key. Battery level accuracy is improved during the first minute after booting. The Off key can be used to exit from the Quick Menus. The Status Bar layout has been improved. Fade on Stop/Pause has less dead time, is more snappy. Source code is provided. This is a requirement of the Rockbox GPL licence. Downloads are from the Rockbox Wiki site. See http://www.rockbox.org/twiki/bin/view/Main/RockBox251 for further details.
