hostap should work, ad-hoc should work. by infrastructure you mean that
the card operates as a 'station'? then it shouldn't work (correctly) as
defined by the standard. commercial products tend to implement "mac-nat"
or just simple dumb passthrough (which requires support on the ap side
and is very much like ad-hoc mode).

you would want to look into WDS for a standard way of dealing with
bridging on 802.11
