[x86 setup] The current display page is returned in %bh, not %bl
The current display page is an 8-bit number, even though struct screen_info gives it a 16-bit number. The number is returned in %bh, so it needs to be >> 8 before storing. Special thanks to Jeff Chua for detailed bug reporting. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
