I've only seen the ATXP1 on 0x37 or 0x4e (it only supports two 
addresses), the
0x44 is maybe for another ATXP.

Yes, good idea.

No, it has no register with a device id.

Yes, will be added again.

AFAIK the ATXP3 is the same as the ATXP1 but without VID control. Not 
sure about the ATXP5, I've only a board with a ATXP1. Needing someone 
who wants to test this.

Attansic doesn't answer me. The mainboard manufacturers say they can't 
give information because of nVidia.
