I believe that Neomagic hardware is only capable of sending the exact
same signal to the LCD and the monitor when both are switched on, so
this figures. (The same goes if you only have a 640x480 VGA projector
and an 800x600 LCD panel - even if you are in 640x480 mode the hardware
will send the same 800x600 signal with the black border to both devices.)
One thing you could try with XFree86 is writing two mode definitions -
one for the monitor at 75 Hz and one for the LCD at 60 Hz - and using
both modes in your Screen section. Then, when you switch from LCD to
the external monitor, press Ctrl+Alt+Plus to switch video modes. Press
it again to switch back just before you switch back to the LCD.

PS silly question really, but is it possible using the XFree86 Neomagic
driver to get a 320x240 mode? Or do I have to switch servers and use the
generic VGA device at 320x200?
