No, the IDE driver should be driving PATA chipsets at present, and if it is not, someone should investigate the reason. Turning on PATA support will probably be done soon, for PATA+SATA combined mode situations, but not for others. Flipping the switch causes a lot of cases to switch from working /dev/hdX to working /dev/sdX, which needs to be managed, and not done willy-nilly. Jeff
