I have edited your HOWTO to what worked for me.

=====================================
[1] Download the kernel source from www.kernel.org. Get the latest
stable version (currently 2.6.17.7). Make sure to get the full
source and not just the patch.
(from here on out, I'll assume we're running as root. It is not
necessary to do so until later, but this will simplify things.)
[2] Unpack the kernel
# mv /PATH_TO_WHERE_YOU_DOWNLOADED_IT/linux_2.6.17.7.tar.bz2 /
usr/src/
# cd /usr/src
# bunzip2 linux_2.6.17.7.tar.bz2
# tar xf linux_2.6.17.7.tar
# cd linux_2.6.17.7
[3] Configure the kernel. Since you are only changing one thing,
it's best to start with the default YDL kernel config.
# make mrproper (not really necessary if building the kernel
source for the first time.)
# cp /boot/config-2.6.xx-blah-blah .config
(# make mrproper ) cross out
# make menuconfig
A menu-based configurator will come up -- this is where you need to
tell the kernel to compile support for the bcm driver. For this
step, follow the instructions from the gentoo forum page listed above.
Enable:
Networking -->
<M> Generic IEEE 802.11 Networking Stack
[*] Enable full debugging output
<M> IEEE 802.11 WEP encryption (802.1x)
<M> IEEE 802.11i CCMP support
<M> IEEE 802.11i TKIP encryption
<M> Software MAC add-on to the IEEE 802.11 networking stack
[*] Enable full debugging output
Device Drivers --> Network device support --> Wireless LAN drivers
(non-hamradio) & Wireless Extensions
<M> Broadcom BCM43xx wireless support
[*] Broadcom BCM43xx debugging (RECOMMENDED)
# depmod 2.6.17.7
[4] Build and install the kernel and modules
# make vmlinux
(go get a snack)
# make modules
(go have some coffee)
Assuming no errors above
# make modules_install
# cp arch/ppc/boot/vmlinux /boot/vmlinux-2.6.17.7
# cp System.map /boot/System.map-2.6.17.7
# ln -s /boot/System.map-2.6.17.7 /boot/System.map
[5] Configure yaboot. Open up /etc/yaboot.conf in a text editor,
and copy the section that starts with
image=/vmlinux-2.6.x.x-blah
including all the indented lines below it. In the (now) second
instance, change "image=/boot/vmvlinux-2.6-xx-blah" to "image=//
vmlinux-2.6.17.7" and change "label=linux" to
"label=myhairisonfire" (or whatever name you desire).
[6] Generate boot image
# mkinitrd /boot/initrd-2.6.17.7.img 2.6.17.7
Then run
# /sbin/ybin
to set the changes.
[7] Reboot and pray. Upon rebooting, you'll get the normal choice
of cdrom, osx, or linux. After you choose linux, yaboot will give
you a prompt (only for a couple seconds -- so be ready, or else it
will boot the old kernel).
Press the tab key and the names of both the old kernel and your newly-
built one should appear.
Type "myhairisonfire" (or whatever name you chose) at the prompt
and you will boot the new kernel. If things go bad, you can return
to the old kernel by rebooting.
=====================================
Well, hopefully I haven't made any mistakes. Report back with any
question or problems! The nice thing about building a kernel for
the first time is that it is a win-win situation. Either
everything will work just fine, or you'll get to learn a lot about
how linux works!
