1. ifdef out the restriction that the SiS 900 has only one PHY This is demonstrably false; the SiS 960 super south bridge in PR 18590 has a SiS 900 rev 1 core in it. 2. bitbang the MII for all versions of the SiS 900; this is the only way that the PHYs on this system answer. Also, I suspect that SIS900_REV_960 constant in if_sipreg.h is incorrectly labelled - there were later revisions of the super south bridge (e.g. the 961, 962, and 963), and I suspect the SiS 900 revision code there refers to one of those.
