Ah, right. As regards space requirements, it's the same.

Yes, that was my intention. This would simplify the installation, removing
the need for kernel compilation, and not bloating it with all possible
drivers. But it is not that crucial, and most people want to compile a
custom kernel anyway.

I don't know how these drivers behave currently, and I do not have now the
card which was recognized by both drivers, so I cannot answer that; at least
in past this was a problem.
