Its tight but can be done.  I've build a embedded system that booted
out of 1Meg of flash.  2.4 kernel+initrd that loaded a pcmcia module
for the wireless adapter in the system dhcp'ed up the network and then
pulled down a larger ramfs and kexec'ed into it.
I had to build a custom version of the pcmcia tools with uclibc only
doing the absolute minimum to get the wireless interface up.

IIRC I only had a couple of  Kb left over.
