We definitely won't have all of this fixed in time for 2.6.18.
Do you really mean 2.6.18 or 2.6.19? And while neither NM nor advanced
features may be ready in time for the 10.2 release, even the basic
functionality will quite likely be very welcome when compared to shipping
a 10.2 without any support for these cards.
developers therefore perfer to use the DeviceScape stack.
There is a general consensus that new wireless drivers should use

like the current ipw2100 and ipw2200 can be ported with a reasonable
amount of work to the devicescape stack - the ipw3945 has already been
ported by Intel (still waiting for the release).

I've been following the developemnt of the wireless stack for quite a
while now, and wihle it looked like the (Intel based) current ieee stack
would be the base for a future unified wireless stack, things have
changed significantly and chances are really high that d80211 will be
the future - there has even been the discussion on netdev to make the
switch as early as 2.6.19 (that's why I wrote "might ... one release
So even if it isn't quite ready for prime time now, it looks like it is
very close - and if it makes it into a 2.6.19rcX while 10.2 is still in
beta, I'd like to see a backport going into the suse 10.2 kernel -
that's what I was really aiming at.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
