Thanks for all of the help.

well. I'd now like to be able to modify the distribution by removing specific packages, upgrading certain components to newer versions, and also building in some of my own kernel modules so that they are
included
in my custom distribution. I was wondering if there is any
documentation
that is available that might help me in doing this.
Not really.
More specifically:
1) I'd like to upgrade the kernel to either a newer version of 2.4 or
better yet to the current stable 2.6 kernel. This would enable me to
build the Prism54 drivers into the kernel in order to support 802.11G
cards with the distribution.
2) I'd also like to upgrade the host AP drivers that come with the distribution. The current host AP drivers I believe are not the most recent stable releases. I'm sure the current ones work fine, but some
of
the specific things I need to do require functionality that is only in the newer version of the driver.
These are interesting changes and all of the them can be done, but the process is not documented. Your best bet is to follow existing build scripts as examples, although kernel is definitely not the easiest point to start.
The way kernel build process works now is that it downloads the kernel source, then downloads a tar with various third-party sources and patches and merges them together using a script which is inside the tar file. That's not a clean approach, but keeping entire kernel tree in tla would slow down working with it too much.
3) I'd also like to stick one of my own kernel modules in the distribution and add a /etc/init.d script to load and configure my module when the system boots.
That's easy. init script can be added to build/bin/root/prebuilt-lrp/etc/init.d.
If anyone has a link to any documentation that would help me to be
able
to accomplish this, it would be greatly appreciated. In addition, if anyone has any tips on how to go about doing these things, they would also be appreciated.
Feel free to ask questions to the list, I'll do my best to answer. :)
