Migrating the contents of ./drivers/ide/pci to scsi is reasonable too. This will allow the legacy drivers to die. Taskfile came to late to be really useful, it is now best used as a model to tackle FIS/FPDMA mapping for SATA II. Linus, my professional opinion is to follow Jeff's direction for 2.5/2.6. This will allow Linux to push open source to the hardware vendors. There are several bastardized scsi-ide drivers in ./scsi. pci2000.c,h :: pci2220i.c,h :: psi240i.c,h + psi_*.h :: eata* ATAPI is nothing more than Bastardized SCSI beaten with an ugly stick. Packet-Taskfile is more than painful, and I am not in the fighting mood.
