That's a known issue. However, I'm not sure whether the issue is in
driver doing something incorrect or the older firmware versions just not
working. I tried to figure out what could be wrong, but couldn't find
any errors in the driver. Once I noticed that power saving works with
new firmware versions, I have more or less ignored this issue with old
