This is a pretty decent list. I'm surprised by number 3 though. Most managers just can't keep their control issues from making them constantly nose around what you are working on.
The fact is that most geeks will be proud and challenged to complete tasks or projects. Encourage them to tell you what they've done or what problems they've solved. Even if you don't care, it's important to the geek that someone knows or acknowledges their 'kung-fu' is superior (to the problems they face).
I know I've often solved complex problems with unique, elegant solutions that I am very proud of only to get barely a nod. Just because it seems like a simple problem with an easy fix to you, doesn't mean you're right. Your geek may have pulled off a technical miracle. Find out, be interested, and acknowledge it.
Also, don't assume your way of doing your job is the best way for your geeks to do theirs.
Most of us have a unique personal style and methodology to problem solving and working that we use because it's the best, most productive way for us to work. And we know this is true because we've refined this methodology over the years and we're still refining it. Not to say we aren't open to friendly suggestions. Sometimes an outside view can see things we've missed.
I have had managers that like to walk up unannounced and say "hey, what are you working on?". The problem is I'm usually working on 5-6 things at once. Many of which are precursors to solving the problem you asked me to solve. But it's not often easy to explain the mental juggling act that I use to problem solve, and constantly interrupting me often just makes me 'drop all the balls' and have to start over.

Anyway, that's my ramble for today.
