Compared to the price of Fash Cards this is not to bad.

It would be good option (if you could make it available), making the 
Dev board suitable for more developement and applications.  As it's 
8k you could have so much of the Rom code in their and use the rest 
of the decoding for PCMIA cards (1015k with the last 8K over written 
by the rom (if I'm reading you correctly).
