fresh rockbox 3.5 install (+ extras) on 3G ipod:

when turned on for the first time, the screen boots up and after the apple logo, the screen turns completely black. (the contrast is turned up completely.)

I can navigate the menus with the help of the back-light and by holding the ipod at an angle so i'm looking down from the top. using the manual, i figured-out the layout of the menus (as i couldn't read the menu names) and turned down the contrast to a sane value.

after this fix, the problem returns if the config files in .rockbox are deleted in disk mode and rebooted.

could rockbox boot up for the first time with a sane contrast value for the 3G ipod? My current setting is: 36.

this may be related: when booting, even with the correct contrast setting, first the apple logo appears as normal, then the screen turns black with the back-light on and the apple logo is barely perceptible (is that intended?), then the screen goes white for a short time and the rockbox logo appears, and boot-up continues.

thanks. ; )
This task depends upon

this got fixed. the only weird anomaly is that near the end of boot-up the apple logo is still shown with a dark contrast.
