At least one of the chips on the EtherStix and the netstix expansion boards gets quite warm (ok, pretty hot actually). Is this ok?
The SMC91C111 chip gets warm. We do not believe that it requires a heatsink for long-term use, and the heat generated will not impact the gumstix or the expansion boards as long as there is decent dissipation from the board (ie don't encase it in a strong thermal insulator).

A typical plastic case around the boards should not cause problems though (although this might get warm to the touch).

It is best to use 4v wall adapters for configurations that do not include a robostix board.
