Well, Linux needs a files system but it can use romfs for these 
situations.  It is done all the time.

Google for romfs.  Also, look around on linuxdevices.com for more 
information on embedding Linux in this type of hardware.  Also, an 
EXTREMELY good resource for this question is the plug-devel list.  Post 
this same email there and experts will answer.  There are members there 
that do this sort of thing all the time.
