        hello.  Now that Seagate has bought Maxtor, the Maxtor disks exhibit
 the same bug as Seagate disks with regard to LBA48 addressing.
        Although a general fix for such disks has been pulled up into -current
 and 4.0, it doesn't look like a fix for such disks is in 3.x trees.  So,
 here is a diff which covers the new Maxtor disks as well for those of you
 still running 3.X systems.
 -Brian
