It does not appear that the kernel(s) will support the root fs on
tmpfs. Looking through the init kernel code: It boils down to a block
device with real major and minor number or NFS.

Could you set up a ramdisk to do the same thing as /dev/shm? Also,
you'll have to tell the kernel where root is, either a boot parameter
(root=xxx) or with the rdev command.
