Are these two monitors connected simultaneously? If so, you need to specify
the "video" kernel boot parameter twice, once for each connector.
See the boot messages for the connector names (i.e. VGA-1 & VGA-2 or
VGA-1 & DVI-I-1, etc.)
Also, keep in mind that a fixed-resolution display, such as an LCD display,
will probably use only a portion of the screen if the resolution specified
is not the maximum supported. A traditional CRT monitor does not generally
act that way.

Good question. I'm not sure. Perhaps they wanted to speed up transitions
between virtual consoles. Perhaps they wanted more flexibility in text modes.
I don't know.
