i've been told that 640 x 400 IS possible with 256k RAM on the video card.
currently, i'm running a standard VGA monitor with a 512k RAM Paradise 
card that displays 640 x 480 w/ 256 colors (unusual).  Most display cards
try different sync rates for 640x480 256 color modes and thus won't work
with VGA (non-multi-sink) monitors.  I tho't some people might find this
interesting.

What I really want to know is how the heck do you get access to the other
banks of 64k in the 640x480 256 color mode.  I've written a TIFF file 
loader in Assembly that uses the 320x200 mode which uses only 64k of 
video RAM.  could someone PLEASE tell me how to do the bank switching?!?!!

Thanxs in advance.
