Getting 1 MB is as good as we can do for now.
Hmm, that'll get awfully tight :-(
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.
