You've got to be kidding me. Linux uses _all_ ram.

total       used       free     shared    buffers     cached
Mem:    1518       1477         40          0        117        707

#mount -t tmpfs tmpfs /mnt/tmpfs
#df -h | grep tmpfs
tmpfs                 760M     0  760M   0% /mnt/tmpfs

#mount -t tmpfs tmpfs /mnt/tmpfs -o size=100M
df -h | grep tmpfs
tmpfs                 100M     0  100M   0% /mnt/tmpfs
