 mmm.... it's 7 pins: relatively speaking, that's a hell of a lot.

 i _could_ suggest dropping one of the LVDS channels, but that would
rule out being able to connect to dual-channel (1440x900) LCD panels
without expending extra cost.

 but, since discovering that there's VGA (!!) _and_ TV-in (!) on this
CPU, i'm considering advocating adding that 2nd expansion header.

 it'll be damn tight for space, though.
