[ltp] DVI problem again

 From my T42 with the 7500 and trying with different hi-res LCDs:
1. The DVI can't drive displays with a res >1280x1024.
2. The DVI and LCD do not work in parallel - maybe it's the same 
circuit, because I could never turn them both on.

As with the windows drivers it's the same, I think those are limitation 
of the 7500...

With the T43p and the V3200 (M24) it is quite easy to go over both problems.

Cheers,
Dragos
