Ok, I already found a bug, occasional lockups on boot and when setting
the backlight. I uploaded a new version at:
Here's a 3rd version. It may or may not help, as I didn't have a chance
to test this one on either albook or ibook g4 yet. I added saving and
restoring of a few more registers that may fix the Xv problem (or not...
depends what X does at this point) and eventually some corruption
problem (the bandwidth related registers weren't restored).
This one caused problems for me. Looks like the backlight got turned off
at boot, I had to sleep it and wake it up to get it back.
I've seen that since the first version. I also have to restart
pbbuttonsd to make it work again after sleep. I keep logging in on tty1
to run 'fblevel 15'.

Actually the backlight tends to turn off some time later, too. It's not
just that it's off after sleep.
