Have you had a look at uClinux? It has already been ported to the ARM7TDMI.
Until now, it is finished for the Aplio/Trio and Netarm. Various other ports are in
progress. Currently, I try to get it running on the Atmel AT91M40400, with the
Atmel board EB01. Have a look at my "uClinux Directory" at 


You will find links to ARM information under Architectures/ARM7. You have to 
take care about structure alignment, see the recent discussions.
