nv driver does not work even with cards it supposedly can work, for example 
with chipset GeForce 6600 GT (in 2-card SLI configuration).  After installing 
fresh Flight 6 AMD64, X.Org is already configured to use nv but it can not 
start. Some fragments from Xorg.0.log (they show that video memory 256 Mb on 
each card has not been detected at all, etc.)

Fatal server error:

These same physical cards work OK in SLI mode and correct glx in another 
distribution (Mandriva 2006 x86-64) when current nVidia drivers are 
installed. How this should be done in Ubuntu Flight 6 AMD64?
