Ah, ok.  That's not a lot of physical memory by today's standards, so I 
can see
why you'd want to avoid running anything extra.  I would, too.  If 
augmenting
the RAM isn't an option then yeah, I'd avoid running anything like Gnome or
KDE (although a lighter-weight window manager would probably be ok).
