As well, only 0x01 capability set. According to Intel's Mobile 915 PM/GM/GMS and 910GML Express Chipset Datasheet, we'll get such a picture on every chipset from this product line: they define power management capability (0x01) as the only one, see 7.2.29 PMCAPID - Power Management Capabilities ID PCI Device: 2 Function: 0 Address Offset: D0h Default Value: 0001h Access: RO Size: 16 bits Bit Access & Description Default 15:8 RO NEXT_PTR 00h This contains a pointer to next item in capabilities list. This is the final capability in the list and must be set to 00h. 7:0 RO CAP_ID. 01h SIG defines this ID is 01h for power management.
