 	Hmm, what is the output of 'sysctl machdep', and can you confirm

 	Thats pretty good going with only 4MB of RAM before framebuffer and
 	kernel is taken away...

 	OK, a couple more tests on the client:

 	a) run 'ls -ld /swap' - can you confirm it sees it as a directory

 	b) run 'mount g21:/export/sun350/root /swap' - it should mount
 	   another copy of the client's root filesystem on /swap on the
 	   client. Assuming that works just 'umount /swap'.

 	c) does 'swapctl -A' give the same 'not a directory' error on
 	   the client (or server)
