I hacked a logitech mouse driver to work in 320x240x16, which is similar
to mode X.  Basically, you need to look for some kind of table which is
used to set all of the info based on what graphics mode you are in.  
Since I was using a hacked version of mode 0dh, I changed the table for
mode 0dh to have 240 vertical resolution  Then you get the problem about
where to store the square that is under the mouse cursor.  Usually it is
stored at the top of the second page (in the driver I was hacking it was).
So you need to move it somewhere else... (compute the address of the top
of the second page, search for it, and change it to the top of the second
page in mode X.  You will probably make several incorrect changes, but
try doing each change one at a time, testing it each time. 

You might also try writing all of the important data into the BIOS
table that keeps track of all of the graphics mode info, and hope that
your driver looks at that instead of just using the graphics mode number.

If you want something that can be used on other computers than your own,
then you probably have to either write your own mouse driver, or find
someone that will write one for mode X...
