In a Perfect World, the kernel should take care of the actual low-level
device-driving, not the X server. Kernel bloat might be avoided by
having a basic VGA driver in the kernel, and loading an LKM for the
right video card once you need to get more out of it.
The problem is, that it would be a big effort to keep track of all available
cards. Currently, the XFree86 folks do it for us, I am not complaining ;-)
