Aha.  I never thought that the flash chip might not hold a partition table 
on the first sector.  If there's no information on the chip itself, I 
suppose auto-detection would just involve looking for superblocks for 
known filesystems and/or the header associated with special sections like 
the nvram, right?

I can see that.  While my personal itch is my WRT54G 1.1 (16M ram, 4M 
flash), I'd like to be able to contribute to a larger project that would 
also support my friend's WRT54G 2.0, the newer WRT54GLs, and devices from 
other manufacturers that have similar CPU/ram/flash limitations (be they 
home routers or not).

Perhaps I just need to add my efforts to the OpenWRT project.  Or, maybe 
the other projects mentioned on the list like embedian.

Yeah, the main issue I have with OpenWRT at this point is the lack of 
stable 2.6.x kernel support.  But, on further investigation it looks the 
next whiterussian may have that -- or at least the development is headed 
that way, so perhaps I just need to jump into kamakaze and see if I can't 
get something running, just gotta make a JTAG cable before I try and flash 
the system.

I would like to see a mips+embeded under the debian banner, at some point,

I'll start with the tarball provided by ths.  Thanks for the offer.
