suspend/resume problems: NetworkManager and iwl3945/ipw3945

As I mentioned in an earlier message, I'm running Fedora 7 (x86_64) on a
Lenovo X60 with an Intel 3945 wireless card.
I started with the iwl3945 module that the installation set up, running
NetworkManager. The wireless network seems to work fine (with WPA2-PSK), at
least in the one location I've tried so far, but suspend (and hibernation)
don't. I found various suggestions on the web (including the quirks, which
don't seem to be necessary for this machine) and it seems clear that the
iwl3945 module must be removed before suspending. But that seems to be
impossible with NetworkManager running. I've tried various ways of
removing the module (manually, in the SUSPEND_MODULES line
of /usr/lib/pm-utils/defaults, etc.), and it doesn't seem to get removed,
causing the suspend to hang.
If I stop NetworkManager, pm-suspend will remove the module correctly and
re-insert it on resuming. Then I have to manually start NetworkManager and
it connects to the network. (I can do this with a script, of course,
though then I have to figure out how to get my script called when I shut
the lid, etc. Where is this stuff now that it's not done through acpi?)
I also tried the ipw3945 stuff from ATrpms. Again, I can connect to the
network just fine, but I can't successfully suspend and resume with the
network restarting. (In fact, I had trouble restarting the network
altogether with this approach.)
Does anyone have a suggestion? (I'll also ask on linux-thinkpad.) Or
should I just bugzilla it? Against NetworkManager?
