Sure, here it is:

Can we have the driver detect it instead of requiring the users to
force it? I mean, the driver is for the SiS630, and this PCI device
is a SiS630. It wouldn't be obvious to a user that they not only use
the driver, but must force it to use it.

With just some brief testing, it seems to work. Doesn't seem much
faster, but it works.

I'm OK with it being slow for the sake of added stability/reliability.
