All video cards should respond to the vesa driver. Trolling 
thru /var/log/Xorg.0.log with 'less' will answer that question. But vesa 
has I believe a max resolution of 800x600 so while it will work it will 
not work to the cards or monitors real capabilities.  There 2 schools of 
thought, one being to go get from Nvidia, the correct driver for your 
card.  But that driver does not play nice with applications that need 
realtime or near realtime kernel performance as it can lock other 
processes away from the kernel by disabling IRQ responses, sometimes for 
hundreds of milliseconds in its efforts to give you fast graphics. 
Nvidia has been kind enough to throw some friendlier code over the legal 
wall which has allowed the linux folks to write drivers for these cards, 
and that driver is much nicer to apps that need realtime access to the 
kernels services. By not hogging the IRQ's.

This driver, called "nouveau", is available from most all the distro's 
and can be installed directly from the repo's with the distros favorite 
package manager as soon as you get a working network connection going.

Thank you for the flowers, Richard.
