Well, for one, I can't use minstrel on it?

maybe its a hardware or firmware limitation.

A driver can opt in to using minstrel, or it can do it's own rate control. Iwl does the latter (not sure if it's in the driver or in firmware). Not sure what it would take to get the Intel drivers to use these changes, but I don't think it's trivial, unfortunately (my laptop also has an Intel card in it).

Let me point out a link to a talk that describes the enormous technical debt that needs to be paid down in just one (other) wifi driver set in order to make forward progress:

These sorts of issues are almost universal in wifi, in every chipset and OS.
