It is true that this has been discussed before, but never seen anybody 
suggesting this:

One way to get maemo running on a display of 320*240 would be hacking 
little bit X server (or the display driver) to pretend to be 800*480 and 
do actually some downscaling when the data goes to display. Depending on 
what kind of hardware you have (whether it can perform graphics 
downscaling operations etc), you might want to consider how to downscale 
(like pixel skipping vs interpolation, basic speed vs quality dilemma). 
Anyway no matter how you actually scale that thing, you will be still 
losing pixel data.

But again, if your display is half*half of original dimension, the 
scaling shouldn't be that ugly, especially when the UI graphics are 
pretty large.
