At least sending multicast/broadcast frames immediately after DTIM
beacons. This is needed for clients in power save mode.

No idea. I recall Intel talking about having patches to support AP mode
for iwl3945, but quick googling didn't reveal anything. All I found was
this from Tomas:

"We've enabled only iwl4965, not so ever effort was done for iwl3945

[...]

In general there should not problem to extend AP mode also for 3945 on
PC platform"

It would be really nice to get AP mode support for iwl3945.
Unfortunately I don't have any spare time to work on that, but if you
are planning to work on it I (and others) can give you email support via
this mailing list.
