Custom Linux Build with Wifi, Touchscreen, and Firefox

I have lurked for a while, but today put together a very brief page about the custom Linux build that I put together for the DT366 some time ago.
I think the information contained in the build script will be more valuable as opposed to the build script directly.
The system is a read-only file system, ramfs filesystems used for run-time operation, boots to a full screen Firefox, with WiFi. The touchscreen works, and the calibration routines are included and work. To use the calibration routines, the filesystem must be re-mounted read/write so that it can write the new calibration values.
I'll try to help and support any efforts related to this.

Hats off to you Sir!
Wonderful work! I had often thought about a LFS approach however my last run around with PenMount left a pretty bad taste in my mouth. Tried to use tslib unsuccessfully in making the touchscreen operate.
I have a ton of questions however let me start with only a few.
How did you get the touchscreen operating?
Do you run xorg? Or outside of FF is it a terminal interface?
What percentage of disk (assuming 500 - 512mb) is taken?
Again, nice job!

For the touchscreen I used the TouchKit-2.03.1712-32b-k26.tar.gz package from
www.egalax.com.tw (new address???
http://home.eeti.com.tw/web20/eg/Touch_Drives.html). This is compiled as a kernel module and Xorg driver. I did have to blacklist a couple of the standard touchscreen drivers.
It is running Xorg with TWM as the window manager. At one point I started working on upgrading to FF5 from FF2, had it all working except that FF was no longer full-screen-ing right. I got as far as thinking I needed to move to a newer window manager to fix that problem.
After stripping most of the doc/man/src and debug/extra information from the executables and libraries, the image is around 360M (with FF5). I have it in my notes I was around 260M (would have been FF2).

I'd like to give this a shot. I am totally looking for something very light like this for my home automation.
Would it be easy to add festival to it? I need the tablets to log into my festival server to remotely play voice commands.
Thanks.

This looks like something that would be easy for a well educated person in linux, but that I'm not, would it be possible to get a step by step,
on Howto put this all together and put it on my WEBDT366. Please help
