As of 10.0-REL you can use the usual multiplier suffix letters in the 
size (and other size related fields), which is easier than writing the 
size in bytes. This is my fstab entry

tmpfs		/tmp		tmpfs	rw,mode=01777,size=512M 0 0

A quick look at the svn repository suggests you do this with 9.3-REL as 
well. I've no idea whether earlier releases let you do it.
