There are definitely exceptions. I know it's early days in my new job, but my boss is female and so far she's been very good indeed. I think part of what helps is that she's the CEO, and the structure of the company is incredibly flat. There's literally her and her husband as the two founders, and then everyone else. There are also only about 25 people in the company so it's relatively small.
I do love Jason Fried and what he and DHH have achieved at Basecamp / 37 Signals. He's long been outspoken about the advantages of remote teams, and a central part of that is about leaving people to get on with their work.
