We've had that exact discussion a few weeks ago, and I objected to this change as there is no possible way you can know for sure people don't use mainline with an old firmware. The whole point of the firmware is to be an abstraction for the kernel, for better or worse. If you really want to do something useful here, consider detecting such firmware (even better, detect the new ones that don't require this stuff) and document the various requirements. At least we'll know where we stand, because the changes you're making are just as random as what we have so far. Thanks, M. -- Jazz is not dead, it just smells funny.
