Ok, here's what I have now, won't wait until I have the FreeRTOS stuff done.
Below are my notes on what it takes to get to the point of having gdb talking
to an LPC2148 target through an Olimex USB JTAG interface.
Note that I'm running Debian 'unstable', and I have a fairly rich build
environment installed. You may need to iterate some installing more packages
to flesh out the build dependencies.. take notes about what you have to add,
and I'll be happy to incorporate them when I get around to stuffing this on
my wiki. Should be fairly easy, since my "notes" are loaded with the actual
commands I issued in cut'n'paste form. I've already used these to get the
toolchain up on a second machine here (one each i386 and amd64), so I'm pretty
sure they'll work if you have the right build deps installed.
Enjoy!

- try it "my way", with some hints from the notes at http://www.gnuarm.org/
Make sure /opt can grow by 700meg+, plus need ~2G for sources and build tree!
Fetch upstream bits, and populate a Dist/ directory

Unpack upstream bits, and prepare build environment. Resurrecting the
"one-tree" script would make this more efficient, but compile cycles are
cheap enough that it's probably not worth worrying about...
