One more thing:
@@ -33,6 +33,7 @@ enum sis900_registers {

flctrl=0x38, //Flow Control Register

This implies that CFGPCMSR is an I/O space register.

And in sis900_set_wol:
+ pci_read_config_dword(sis_priv->pci_dev, CFGPMCSR, &cfgpmcsr);
+ cfgpmcsr |= ~PME_EN;
+ pci_write_config_dword(sis_priv->pci_dev, CFGPMCSR, cfgpmcsr);
But this implies that it's a config space register. So which one is it?
