Hello,
Are you going to use the ucsimm (MC68EZ328) module? I'm using gcc with newlib 
on a ucsimm. If it would help, I'll email you the instructions.

Are you aware of the uClinux project? They have ported Linux to the ucsimm 
and ucdimm (MC68VZ328), as well as many others. It uses uclibc instead of 
newlib. We didn't need the added complexity of Linux and found uclibc to be 
incomplete.

Hope This Helps,
