That's good to know for the future.  But how did you come up with  
those numbers for the ModeLine entry?  I played around with the  
HorizSync and VertRefresh entries to no avail.

I have not installed the nvidia-installer, but rather I run the  
NVIDIA-Linux-x86-1.0-XXXX-pkg1.run script with the -s option (silent)  
after rebuilding it with the --add-this-kernel option.

I got this to work, but it was a bit of a hack.  I'll contact you off  
list with the details.
