VGA Detect monochrome mode?

[superfury]

Anybody knows how to detect if a monochrome mode (MDA?) (BIOS Video Modes 0x7,0xF&0x11) is active by looking at the VGA registers? I don't want to look at the BDA (because the software might fake stuff or use a custom display resolution, colors etc.) (I want to properly emulate the 2color (1-bit) mode for graphics&text modes in my VGA emulation).

EDIT: nvm, it was the Misc Ouput Register bit 0 (i/o address select) that makes the difference between 16 color and monochrome mode.
