Yep, quite interested in helping/using/testing the code needed to boot up 
BIOSless, from memory mapped flash, w/ little RAM.  I had figured that a system 
with memory mapped flash *COULD* have the kernel's static (read-only) part--
code and constants in flash, and decompress the r/w data section into RAM.  We 
could probably get by with VERY little ram for the kernel this way, although 
I'm not sure how much code vs. data there actually is in the kernel.

I took a quick look-see at the stick.  We'd probably want to add the watchdog 
support into the kernel as well.  And the non-standard clock interface would 
have to be added...  Keyboard support removed, etc.

If the eval is cheap enough I'd probably get one just to 'play' with it.  It's 
too bad it only has serial communications...  Ethernet would be nice.  Then 
this thing could be a firewall for a modem/PPP for a small company...  And I 
wonder if the 16C550's are limited to 115,200 like usual.  (They could be made 
to go 920kBaud over differential lines for some real fun.)

Reguardless, there are some things that can/should/will be done in the kernel 
to help these sorts of embedded systems take advantage of Linux.
