I have installed 10.5.1 using the Kalyway disc on my D610 laptop. Using the iwi2200.zip file I was able to get the wifi working. Everything is working great. My only question is that the OS does not seem to recognize that this is a laptop, and thus it does not show remaining battery life.

Does anybody know how to make this work, or is it just one of those things that will never work?

Powermanagement.bundle. There are plenty of threads talking about it. Two stickies, too.
