I had a class in which we designed a board with the 5206e.  It had a 4MB DRAM module and 
1MB of Flash and ran uCLinux ( www.uclinux.org ).  We used a port of gcc with gdb to 
program it.  Although we had a good teacher to help us out, there were no major snags or 
gotchas.  The Coldfires are pretty nice and relatively easy-to-use microcontrollers.  I 
recommend playing around with them.  If you want to have a look at the class website, 
there's plenty of useful links. http://www.lynch.ece.ufl.edu/EEL5745/5745main.html
