O.K.  The driver help recommended turning on debug for first time usage
and I was surprised when I didn't get any debug output.  And I see now
that /proc/bus/pci/drivers/iwl3945/debug_level *is* writable.  I'm lost in a
twisty maze of /sys directories, all subtlely different.

The driver itself works fine, but I'm having trouble getting decent speed out
of it, similar to the horrible performance I had under another operating
system, not quite as bad but still worse than a MacBook Pro.  Any clues on what
I can look for to see why it so relatively slow?  I'm going to put it to the WoW
test as soon as I can get a modern userland & Wine on the machine, it's running
RHEL 4 now.  The machine is a Lenovo T60.
