Just in case the video BIOS +does something extra screwy, read the cursor position back from the +BIOS instead of relying on it doing the right thing. + +While we're at it, make sure we cap the cursor position to the new +screen coordinates. + +Reported-by: Wim Osterholt <wim@djo.tudelft.nl> +Bugzilla-Reference: http://bugzilla.kernel.org/show_bug.cgi?id=15329 +Signed-off-by: H.
