agp_collect_device_status - determine correct agp_cmd from various agp_stat's : an agp_bridge_data struct allocated for the AGP host bridge. : requested agp_stat from userspace (Typically from X) : current agp_stat from AGP bridge.

This function will hunt for an AGP graphics card, and try to match the requested mode to the capabilities of both the bridge and the card.
