You can also try this.  1600x1200 is not a standard VESA mode but is most
probably supported by your card as an OEM mode.  However, we do not know the
mode id of 1600x1200 since it's different from vendor to vendor.  

You can use X though to find out what modes are supported by your Video
BIOS.  

1. Boot with DVI attached
2. Change the X driver to 'vesa' (instead of probably 'nv')
3. Launch X
4. Check /var/log/XFree86.?.log
5. Find the mode id you want, add 0x200 and use it in your 'vga='
   boot line
