Added "options ATA_STATIC_ID" that wires ATA disks like the old wd driver. Fixed problems: Dont use more sectors/intr than the drive supports. Fix announce of > 8.4G disks. Dont call ad_interrupt/ad_transfer when no disks config'd. Use the right page# for CDR write mode params. Fix breakage when no PCI support in kernel. Implement DEVFS stuff. General code clenaup.
