Command line has gone

Hi!
I've a Mandrake 9.1 distro and one Matrox P650 Graphic Card, I've
intalled the drivers for this card (and it recompile my kernel) and
I've used one of the XF86Config-4 sample files for use 2 screens and
it work, but I've lost the command line terminals (ALT+CTRL+F1..F4).
I've tried a lot of modifications on the XF86Config-4 file to fix it
but without sucess. When I change to one of those terminals the screen
goes black and it apears the following message:
"Out of Range
Optimum mode: 1600x1200 H=75.1KHz / V=60Hz"

I think that it use a refresh rate that is higher for the screen but
I've tried a lot of changes in the files...

The 2 screens are HP-2035 Flat Screen 20"
and the current XFConfig-4 file is
