As you probably noticed, I have submitted a patch to clear 0x41 in the PCI
configuration space.

More to report on the "ssh user at ipaddress bash -c 'cat > /dev/null' < /dev/zero"
test. If I issue it on the netbook using the IP address of a computer connected
to the AP with a wire, it does not fail. So far, the test has been running for
nearly 24 hours. When I log into the wired machine and issue the command using
the netbook's address, then it fails after 20-22 minutes when it gets the "No
probe response" message that I reported earlier.
