 =>Is there a BIOS setting to configure the aperture size?
 
    I believe so. However, the problem isn't the size, it is that
 the wrong driver attaches, and I assume the aperture size is being
 pulled from the wrong place. My "fix" is just a workaround for the
 fact that the value it gets is zero, which is divided by two _ad
 infinitum_. I'd argue that it is a reasonable boundary test in any
 case, and working around the bug is a useful side effect. The same
 condition could occur normally if the BIOS settings let you set
 the aperture size to zero, in which case you would want the same
 error.
