SII3512 rev0 ?

[Peter B]

In /usr/src/sys/dev/ata/ata-chipset.c the table (ata_sii_ident) for
Silicon Image chips:

                  pcirev
 { ATA_SII3512,   0x02, SIIMEMIO, 0,         ATA_SA150, "SiI 3512" },
 { ATA_SII3512,   0x00, SIIMEMIO, SIIBUG,    ATA_SA150, "SiI 3512" },

Indicate there is a revision 0 of the chip SII3512. I wonder if there exist
such chip, or if this is just an assumption from the problems with
SII3112 rev0 ..?

Any input on the reliability of SII3512 is also welcomed.
