When I boot to GNU GRUB on a dual-monitor Dell Optiplex 990, and it displays on both screens, then when I cursor to select the desired boot option, the apparently selected item differs between the two screens.

Sounds like one of the screens is showing from the second VRAM double-buffered image. Correctly solving this requires dual-screen support and especially parsing VESA dual-screen info. Not sure if at all possible and if so it will be a lot of code changes. Postponing to after 2.02.
