The module sounded like a good idea,
the problem I have(not sure if this is kernel related)
is after the network is up, loading anything takes
a good 30's, then after about 15min later my router will
do a reset(disconnecting any machine connected). could be something missing
with wpasupplicant, kernel, some lib, who knows...
(at this point my main goal is to get the rest of
the system built before dealing with quirks).
