I havn't tried 800Mhz hardware, but I have extensive experience with the
266Mhz c3 in the WRAP board for comparison.  The 266 Mhz part has no
heatsink, but I've found it to be flakey in "hot" environments if a heatsink
is not rigged to it.

So... the WRAP boards have 3 "sis" interfaces.  With various combinations of
usage, one can expect 30 megabit of average sized packets if they kernel is
doing the passing.  This makes the board an adequate wireless bridge.  If
userland is doing the packet passing (pppd vs. mpd as a DSL router), I've
had trouble getting more than about 10 megabit through the unit.  This makes
it an adequate DSL router but poor for aggregating multiple links.
