The only reason for this change is to make a mark at the kerneloops.
I.e. users know, there is a bug. Developers know, there is a bug.
Everyone knows that there is a bug, but until it is at the special place
we look to each other just like there is no bug.

Here are dumps for example:
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=245

Bug existed even with 1.2 firmware and .11 kernel.
Intel, that's a great marketing slogan: stability everywhere!
