PCI: Compaq Evo D510 SMBus quirk using USB instead of VGA
David O'Shea [Mon, 2 Mar 2009 08:51:13 +0000 (09:51 +0100)]
On the Compaq Evo D510 SFF/CMT, a PCI quirk activated the SMBus device
based on detection of the on-board VGA controller, but the on-board
VGA is disabled if an AGP card is inserted, so look for one of the USB
controllers instead.
