Bug#602536: useless /dev/cciss/ device

[Ian Jackson <Ian.Jackson@eu.citrix.com>]

Package: linux-image-2.6.26-2-686-bigmem
Version: 2.6.26-25lenny1

On an HP DL165 with nothing connected to the CCISS controller (the
disks are connected only to the ordinary SATA controller), this kernel
produces a device node /dev/cciss/c0d0, without a corresponding entry
in /proc/partitions, but with an entry in /sys/block.

(parted sees this and complains about it, and it makes automated
installs awkward.)

The device can be opened but looks empty:

  woodlouse:~# dd if=/dev/cciss/c0d0 of=t
  0+0 records in
  0+0 records out
