On Redhat Linux 6.1, I changed the case statement in vice-setup-rvm just
after the LOG file is created to the following:

case `uname -sr` in
        "NetBSD 1.2" )
                rvmstart=0x20000000 ;;
        NetBSD\ 1.3* )
                rvmstart=0x50000000 ;;
        NetBSD\ 1.4* )
                rvmstart=0x50000000 ;;
        FreeBSD\ * )
                rvmstart=0x50000000 ;;
        Linux\ * )
                rvmstart=0x50000000 ;;
                rvmstart=0x20000000 ;;

And rvm setup now works!

Many thanks

  The problem isn't necessarily low memory, instead that RVM tries to map
its data segment at address 0x20000000 and fails because something else
(like a shared library) starts less than 22mb above that address. Since
RVM is not smart enough to find a free address range by itself, you have
to pick one for it. 0x50000000 is the default in vice-setup-rvm for other
OSs, it might be  a good one to try first. If not, you can examine a few
of the /proc/<pid>/map as described a few posts earlier. 

Good luck
