It is specifically a problem in the laptop's BIOS. There are Dell laptops that suffer from this shortcoming as well. So it isn't an XFree86 bug, but rather the lack of a certain "feature" that shouldn't need to exist in the first place if they made the laptop BIOS correct in the first place. Thats how I understand it anyway. If believe the XiG X server works around this issue, so it should be possible for someone familiar with the driver to add support as well given access to the necessary docs from Intel, etc. -- Mike A.
