[ltp] Dual monitor setup: T40p+XFree-4.3.0

[Paul Kaplan]

The card is a Radeon 7500 w/ 32Mb of vram.  According to IBM it supports 
2048x1532 output, twice the size of the internal panel.  Windows does not 
indicate that two screens are available (all I can do is set the same output 
to display on one or both screens), but I'm not convinced that there's not a 
setting required to activate it.  Any other way to determine whether multiple 
FB are possible?

I would be happy to setup X either to output different content to two 
monitors, or to have a single desktop that spans both monitors.  But from 
your comments it sounds like I'm more likely to have only the latter option.
