There have been some hardware and kernel changes since the
previous entry:

 - USB and firewire drivers have been removed from the
   kernel (they're not needed because this is a headless
   server), so they don't appear anymore in dmesg, and
   the driver is reported as "none" pciconf output.

 - The hard disks have been replaced with different ones.

 - A DVD-RW drive has been added.

 - A SCSI adapter (Symbios 810) has been added.
