I now retested with a fresh pull from Linus's repo (2.6.31-rc5) and I see the same behavior with Fn+F5 not changing the wifi radio status at all. I do not know why we would see different behavior considering we have the same platform and running the same kernel. I found one related option in the BIOS, but with that I was only able to have wireless HW rfkill permanently enabled. I am not sure about the original problem though. In your original report you mention that you are unable to use wireless due to rfkill. From your email it seems that you are able to toggle wifi rfkill state using the Fn+F5 keys, so with that disabling rfkill you should be able to use your wireless. Can you still not use wireless even when rfkill reports "RFKILL event: idx 6 type 1 op X soft 0 hard 0" ? Reinette
