Heh.

I wouldn't know, I never used gentoo, but I doubt it.

Personally, as you can see on my homepage, I use 2.6.11.7 + patches. You
shouldn't run a vanilla 2.6.11(.X) kernel on a new powerbook, too many
things including temperature control won't work. Please see
http://johannes.sipsolutions.net/PowerBook.

I don't think I see the second port either, but I'm not sure (don't have
mz PB here right now). But I think the keyboard is on the first, and
bluetooth on the second and third or something weird.

Ugh. Don't use devfs. udev works just fine, and a bluetooth usb device
does not create any nodes in /dev unless you have rfcomm enabled afaik.

What happens if you load the appropriate modules (usb_hci or hci_usb or
whatever it is called) and then try hcidump?
