Both you and Calvin have sent a couple of replies off-list. I'm
guessing that was by mistake, so I'm taking the topic back on-list.

Well, you don't have the necessary files yet.

Breezy was first available when the development on it began, even
before the Hoary release in April. I know you haven't had the iBook
that long. If you used the bluish CDs that Jim Dennis burned, that was
the third "Colony" release of Breezy, shortly prior to the "Preview"
release, both of which have already been greatly obsoleted.

You say it has a Prism GT chipset, and Calvin says it has a zd1211
chipset. Are you sure you have the same dongle? If you have the exact
model# of any 802.11 device, you can nearly always determine its
chipset at <http://www.linux-wlan.org/docs/wlan_adapters.html.gz>. It's
best not to click that link unless Firefox is your default browser,
because you need one that will display compressed webpages, like the
pages on the RUTE site. I really hope it's not one of the Prism
chipsets that need the linux-wlan-ng driver. That's what was giving
Bruce so much trouble with the dongle that he had, and what continues
to prevent José from using the Hawking card that he has. I just tried a
"modprobe zd1211" on my iBook and got no errors, so that module is
obviously there. If that is indeed your chipset, the problem must be a
driver matching issue.

What about a DVD or audio CD?

I keep forgetting that the stock installation has DMA disabled. You
should turn it on in /etc/hdparm.conf, although the difference is not
all that noticeable.

Don't let appearances fool you. It relies on the kernel's handling of
the filesystem, which was barely Panther-compatible for HFS+ when I
last checked, and will definitely cause problems with Tiger. The
filesystem journaling introduced in 10.2.2 and made default in 10.3
AFAIK still isn't handled under Linux, let alone all the new filesystem
stuff in 10.4, so my recommendation is to only mount HFS+ volumes as
read-only except when it's absolutely necessary to mount as read-write
for as short a time as possible, immediately followed by a course of
DiskWarrior 3.0.3 or later. As for HFS-not-plus, support was
near-perfect in the 2.4 kernels, except for formatting them, which
would stuff the superblock full of subtly invalid values. I don't know
whose bright idea it was to rip out most of the HFS code from the 2.6
tree, but there is no longer any way to access either metadata or
multiple forks, where 2.4 gave you a choice of like 5 different ways.
If you need to share files between Linux and Mac OS X on the same
machine, run OS X under MOL, and export a Linux folder over NFS to the
OS X you have running under MOL.
