Except for these lovely intel parts, the 82802? series. I am using one now 
that is low pin count, but 1 Mbyte. how does intel do it? they use 
address/address multiplexing, which in the limit by design will allow 
parts of up to 256 MBYTES (or 28 bits of address if my math is wrong :-0)

Thus we will in the small low pin count package be able to fit linux 
kernels once again. Lots of them! Very nice.

DoC parts just don't seem to be keeping up with these trends, and the
company has been hard to work with, which is why FreeBSD is dropping DoC
support in 6.0. Given the higher densities to come in LPC packages, and
the uncooperative attitude of the DoC vendor, I would say that the 82802? 
series is going to be very popular.
