My lenny picks the wrong resolution whereas squeeze is right

[T o n g <mlist4suntong@yahoo.com>]

Hi,

My lenny picks a smaller resolution than my monitor can handle. Almost 
like http://article.gmane.org/gmane.linux.debian.user/376362, but my case 
is different. 

The good news is that my squeeze picks the right one, for the same 
machine. I've posted the brief comparison of the 2 logs at 

http://paste.debian.net/plain/89783

The executive summary is, 

lenny says:

  (--) NV(0): Chipset: "Unknown NVIDIA chipset"
  (II) NV(0): 1280x1024@75Hz
  (II) NV(0): Modeline "1280x1024"x59.9  109.00  1280 1368 1496 1712  
1024 1027 1034 1063 -hsync +vsync (63.7 kHz)
  (II) NV(0): Not using default mode "1280x1024" (width too large for 
virtual size)

while squeeze says:

  (--) NV: Found NVIDIA GeForce 6150SE at 00@00:0d:0
  (II) NV(0): Printing DDC gathered Modelines:
  (II) NV(0): Modeline "1280x1024"x0.0  108.00  1280 1328 1440 1688  1024 
1025 1028 1066 +hsync +vsync (64.0 kHz)
  (II) NV(0): Modeline "1280x1024"x0.0  135.00  1280 1296 1440 1688  1024 
1025 1028 1066 +hsync +vsync (80.0 kHz)
  (II) NV(0): Configured Monitor: Using maximum pixel clock of 140.00 MHz
  (II) NV(0): Estimated virtual size for aspect ratio 1.2333 is 1280x1024
  (II) NV(0): Clock range:  12.00 to 400.00 MHz
  (II) NV(0): Not using default mode "1280x1024" (hsync out of range)
  (II) NV(0): Modeline "1280x1024"x60.0  108.00  1280 1328 1440 1688  
1024 1025 1028 1066 +hsync +vsync (64.0 kHz)

Any way for me to have my lenny to use the right resolution? It's 
damaging my monitor.

PS. both of the full log can be posted if you want.

Thanks
