[Soekris] [soekris] net4826 + two 400mw miniPCI?

[Jim Thompson]

1) there shouldn't be any problems powering the miniPCI cards.    
miniPCI provides a spec for several things, including max current @  
3.3V (the only
voltage allowed on a miniPCI connector).    Soekris and other vendors  
of similar boards have adequate on-board power supplies, assuming  
that the voltage
drop getting *to* the board isn't too high.  (Hint, starting with  
24VDC is much better than starting with 12VDC...)

2) If you're planning on running both cards in the same band, just  
give up now.

3) antennas are a whole nuther subject.
