All the Adaptec I2O RAID products use the same driver, including the
ATA(Adaptec 2400A) based one.  The ATA drives/arrays will appear to the OS
as a scsi
device.  The driver was in the last Linus release also (2.4.10). I am
running the adaptec 2400A on a 2.4.6 kernel which i patch with adaptecs
dirvers, with no problems..
