Linux: Dual scan frequency ranges....




Hello,

Yesterday, I played a bit with the latest release of SVGATextMode on my 
TP360CSE running Linux-1.2.0. It's really a nice program. 
I managed to get 80x30 and 80x60 modes. I found it really interesting because 
I can get a block cursor instead of just a line. This is really better on a 
dual scan screen.

Anyway, my question was about the frequency ranges. This program uses a
configuration  file  which is very similar to the XF86Config from Xfree-3.1.

Somes modes need special frequency ranges (>70Hz for vertical) although
there are reported as supported directly by many SVGA Cards.

I wonder if someone konws exactly the ranges *actually* supported by the 
*DUAL SCAN* screen from the Thinkpads ?

My XF86Config currently shows :
HorizSync	20-40
VertRefresh 60-70

May I increase some values ?



Thanks.
