Hi,

for some vendor/id pairs the kernel will autoload both the sis-agp
and the amd64_agp modules as the sis-agp module will load for all
sis devices. This collision causes the bug reported in:
http://bugzilla.novell.com/show_bug.cgi?id=248665

As currently sis_probe does its own matching, requesting the whole
range gains nothing. The clean fix seems to me to leave the matching to
the core and advertise only the devices actually supported. This patch
does so.

        Regards
                Oliver
