The device is small like a linksys router and the Soekris stuff.

I plan to use a 64 meg flash card but this is the first time I have 
looked at m0n0wall.  Anyone have any experience with the axiomtek boards 
and m0n0wall?  If not anyone have any opinions if the hardware is 
supported by m0n0wall?  Any information would be appreciated.  I will be 
getting in an evaluation NA-0041B device within a week or so to test out.
