If it's a one-off effort for one driver, I think it should be possible. 
  MadWifi (current snapshots) supports kernels from 2.4.22 to 3.0, and 
the compatibility layer is not very thick.

Many errors in that log come from the compatibility code you are not 
going to need, such as MSI support.

INIT_WORK changes are tricky, but it should be easier to backport the 
code than it was to forward port it.  MadWifi could be used as a reference.

You probably don't want mesh support.  Try disabling as all the code 
that can be disabled.

I don't know how intrusive USB changes have been.  Basically, until you 
try, there is no way to tell how hard it might be.

compat-wireless didn't go to older kernels because it needs to be 
constantly maintained and because it supports multiple drivers.
