Except optionally for the following for chips not handled by or broken totally in drivers/ide: pata_mpiix - some early pentium era laptops pata_oldpiix - original "PIIX" chipset pata_radisys - embedded chipset The other apparently "libata only" chips are pata_jmicron and pata_optidma. There are patches to handle these as "generic" PCI IDE in the base 2.6.18 tree already so only features will be lost (eg mode switching). As Jeff implies distributions should be using drivers/ide for the Jmicron PATA and the Opti DMA PATA for now. > * /dev/sdX supports fewer partitions than /dev/hdX (16 versus 64, IIRC) > > * /dev/sdX does not support all the HDIO_xxx ioctls that /dev/hdX does. > In practice, the ioctls we ignored are ones that very few people care > about.
