xgifb supports these devices:
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_20
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_27
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_40
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_42

Two of them are already supported by sisfb:
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_20
PCI_VENDOR_ID_XGI, PCI_DEVICE_ID_XGI_40

So I think that support for the remaining two (and missing features, if any) 
should be added to sisfb.
