[En-Nut-Discussion] Ethernut on TI's Cortex-M3 (Stellaris LM3S...)

Hi everyone,

I'm working on a little I/O board featuring an LM3S9D90 and an FPGA. 
Until some time ago I'd planned not to use an OS at all and implement a 
simplistic cooperative multitasking framework on my own. Well, that was 
before I've heard of the Ethernut project which looks very promising for 
this project.

Anyway, I've fetched the latest sources from Subversion and built them. 
I then noticed that there even already exists a dk-lm3s9b96 target of 
which I've got a board for testing. What I (nor the compiler) could not 
find however, is the specific include file for this processor. So my 
question is now if there is already some work in progress for this 
processor and it hasn't been committed yet (or I didn't find it...) or 
if I need to do this from scratch. I suppose I'd need some assistance 
for the latter option, as I've never done this before.

And another thing: Is it preferable to use the cm3-ecross-gcc from 
Thermotemp or the one that ships with TI's stellarisware?
