Me as well.  I think I want to see if I can get a 2.6.0 kernel to run
on x86 without an mmu.  Potentially that could be very nice size
reduction wise.

And to really get it useful I need to put in the extra work to get
kexec into the kernel.  I'm almost there, but I am currently distracted
with freebios2 and the Opteron port.

Now that there is a good general purpose solution to small 256KB ROMS.
I don't feel bad about pursue a solution that is only useful for 512KB
ROMS and above.  A very compelling reason is that hardware is getting
increasingly interesting, and needs more drivers etc.

Though given how things are going I am half tempted to do things like
write a mini TCP stack that is closer to 10K than 100K.
