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. Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
