ac users have reported that the brightness-adjustment
	features in Windows don't work when Windows is booted via rEFInd,
	but that these features do work when Windows is booted via the Mac's
	built-in boot manager. Unfortunately, I have no idea what causes
	this problem, I have no Windows installation on my Macs, and I have
	no way to debug it. Therefore, it's unlikely that I'll be able to
	fix this problem myself; but if you have the equipment and skill to
	do so, I'd be interested in receiving a patch.</l
