Don't think so -- just use 24 or 32-bit colour in the video card, the LCD will 
use the 18 that it can and discard the rest.  Basically the fact your LCD can 
only handle 6 bits per colour is a local issue for your LCD, treat it as if 
it can handle 8 bits per colour and it will use the most significant 6 bits 
of each colour.

X is probably rejecting your requests for better resolution because it 
believes the monitor is not capable of it.  Examine your /etc/X11/XF86Config 
file looking for the Section "Monitor" part and specifically the HorizSync 
and VertRefresh parameters inside that.  Try increasing the second value on 
each and restarting X.
