>Description:
Try to boot a kernel with a sis 900 rev 0x91.
- sip0 will be detect with mac address ff:ff:ff:ff:ff:ff
- no PHY will be found.

This card is detect fine with FreeBSD 5.1 & Linux 2.4 (live CD) ...

From FreeBSD(and Linux) src, it seem that they handle this card in a special way:
from if_sisreg.h
/*
 * SiS 900 PCI revision codes.
 */
...
#define SIS_REV_96x		0x0091
and from if_sis.c
...
else if (sc->sis_rev == SIS_REV_96x) {
			/* Allow to read EEPROM from LAN. It is shared
			 * between a 1394 controller and the NIC and each
			 * time we access it, we need to set SIS_EECMD_REQ.
			 */
...
