Nothing like a challenge to get results! :)

It's going to be tight in there!  You might want to consider enabling 
the non power-of-two allocator in the kernel config - it will make more 
efficient use of the limited memory resources.

Yes - you should basic MTD support, only do support for RAM devices 
(don't bnother about intel or AMD flash support yet), and in the 
mappings section, choose the uclinux mapping.  That should be enough to 
get it going.  You will also want to enable ZFLAT binary support in the 
kernel config, and make sure in the vendors Makefile 
(vendors/XXX/YYY/Makefile) that you are running "mb-flthdr -z" over all 
applications, to shrink them down as much as possible.

Keep up the good work! :)

John
