Just to give you an idea of memory usage: a 256 MB ARM Debian etch (QEMU)
system is using 17M of memory when logged in. With XFCE launched and one
terminal window the usage is 76M. Launching Lazarus (gtk2) and after
compiling a small program (8 units in editor), memory usage is 84M. Usage is
what you get with the free command: used -/+ buffers/cache. 
XFCE is small but there is much smaller. I've taken Lazarus as big/huge
program not knowing what your project involves.  The system in not optimized
neither as you would for a real embedded system either (lpd and other
daemons running).
