iBook2: mostly working

["Mr. Stuart Lamble" <lamble@silas.cc.monash.edu.au>]

(Sounds like a Douglas Adams novel of some sort, doesn't it?
*ducks* Anyway.)

I recently (two-three days ago) purchased a brand-spanking
new Apple iBook (the new model, that is, not the original.)
I have installed Linux upon it, and so far, things are going
reasonably well. There are a few little niggly things,
though, and I'm kinda hoping to get a bit of advice from
anybody out there who's a bit more clued than I am at the
moment. (my Linux experience is mostly x86, rather than
Mac.)

Background: installing from the potato CDs (oh, ok, just the
first potato CD), then upgrading over the Internet. (Having
access to a fast 'Net connection at work is *nice* :)

  * Keyboard: When X boots up (see below), it works nicely.
    If it doesn't, though (or if I switch to a text
    console), it doesn't map the keys correctly. I know that
    this has something to do with CONFIG_MAC_ADBKEYCODES,
    but I can't remember the details off the top of my head.
    I'm pretty sure that the kernel I'm currently using has
    this parameter unset.  IIRC, the first time around, when
    I upgraded I was asked if I wanted to change the
    console's expectation of this setting, said yes, and
    promptly cursed myself, because I couldn't type anything
    (call me stupid :) The second time around, I didn't --
    but now that I'm ready to make the switch, I can't
    figure out how.
  * X: I have a USB keyboard and USB mouse. Sometimes, X
    recognises (and accepts input from) the USB keyboard;
    other times, it insists upon the laptop's own keyboard.
    I'd really like to be able to use both at once (so if
    one's missing, I can use the other without fiddling with
    the config file -- eg, when I'm on the run.) The
    trackpad is working, but it is *extremely* sensitive.
    I'd also like to get the USB mouse working, so I can use
    a mouse with more than one button (as Ghod intended :)
  * Booting: yaboot doesn't seem to like the configuration;
    it can't find the kernel. If I type in the full path
    (hd:14,/boot/vmlinux-2.4.5), it's happy.

Kernel version: 2.4.5. Otherwise, it's pretty much bleeding
edge Debian packages (I have this tendency to ignore the
Debian kernel package; this dates back to when I first
started using Debian.)

The only remaining wishlist (apart from the above, which are
purely configuration issues) is sound. Ah, well, I can
wait.. but it's no fun playing Railroad Tycoon without the
sounds... *sobs* :)

Many, many thanks in advance.
