Like the iBook there is no power management yet, the new

 PMU is undocumented and hasn't been reverse engineered. Ben's
 iBook has a dead hard disk which is holding up his efforts,
 though he seems to keep pretty busy on other projects...

yeah, not difficult to find things to do ;)

The LCD display is bright! There are no brightness or

 contrast controls yet, the question that needs to be
 researched is whether these are controlled by the PMU or
 the Rage Mobility's power management facilities.

Well, I think it's the ATI chip. The device tree is full of

backlight-control = "ati"

stuffs and there's no backlight node under the PMU like there used to be
on other machines. I'll look at the docs, I hope it's not wired on the
GPIOs...

Sound??? Haven't tried, haven't even inquired as to the

 iBook's status.

The device tree says it's an awacs/screamer on a davbus, like my G4, and
mine works. There is probably some trick to power it up since it's a
powerbook, but the chip itself is not the i2s stuff of the ibook for
which we don't know anything (yet). We just need to find out how to power
it up.

USB traps: some combinations of the keyboard and mouse I have

 will work on one boot and cause a trap on the next (I think
 the mouse, a Logitech 4-button scroller is causing the
 driver's confusion).

Well, the USB stack we use is a backport of an old 2.3.x stack and may
still have problems. It works for me but I use only a MacAlly kbd and a
basic low cost 3 btn mouse.

PCMCIA/card slot: there is a new PCI bridge used that will

 need support.

It's a TI1210, I think it's the same in the Lombard.
