How about using a parent class, and having all drivers for new cards
etc. as children of that class.

The base class would work thus:

class videoDriver
{
protected:
	// some stuff
private:
	videoDriver();
	~videoDriver();
	.. .
	// other virtual video functions ....
};

then you can derive all your new drivers from this:
class S3videoDriver : public videoDriver
{
	....
}


then you can do...

void main()
{
	videoDriver	*pvdVideo;
	pvdVideo = new S3videoDriver;

	S3videoDriver->....  // some driver type operation
	.. .
}


Any good do you think?
