How much is tons of kernel memory?

The application where I'd like to use devfs is on install floppies.
If the load footprint of devfs is < 23k, I've won over insmod
(not even counting the additional footprint needed for the module)
and I've won bigtime over a userspace solution that wants to
include /bin/sh (64k)
