Bug#593183: I am wrong, I do not see rt2860sta broken by 2.6.32-18.

[lsorense@csclub.uwaterloo.ca (Lennart Sorensen)]

After a bunch more poking, it found that 2.6.32-3 and 2.6.32-4 didn't
work on the machine anymore either, so I started suspecting other things.
Turns out network-manager showed every device as unmanaged.  Somehow a
new version of network-manager included a new config file, but it was
left as .dpkg-new and changing to the new one made network-manager start
managing connections again.  Now 2.6.32-5-amd64 version 2.6.32-21 is
working fine with the rt2860sta for me with the latest network-manager
packages (from squeeze) installed and with up to date default config.

The difference that seemed to fix things was the change in
/etc/NetworkManager/NetworkManager.conf from managed=true to
managed=false.
