Right, adding PCI support will solve most of our problems in ata.mod.
Currently, a reset is sent to each device.  If PCI is used, every ATA
device can be found (if they support the ATA/ATAPI standard).  Besides
that, the reset might cause problems.  Perhaps the ATA driver can even
coexist with biosdisk.mod in this case...
