The 4MB DRAM may be a bit of a problem.  Flash doesn't matter as much 
since you can boot it via tftp (for lab purposes).  But most newer images 
require a quite of bit more than 4MB.  The good news is that DRAM is 
usually not that expensive.  Search CCO for 4000 hardware layout.  You'll 
get a lot of hits explaining where everything is.  A visit to memoryx.com 
may not hurt either.
