The raw module is not enabled on s390/s390x
During SLES9 and SLES10 development IBM filed bugs about the missing raw
driver. Avoid that for SLES11 by adding it to the other char driver
entries.

The raw driver ist deptrecated amd your friends at IBM should better stop
using it ASAP. It certainly won't survive until SLES11 is due if you
guys stick to your current release schedule.

NACK. The raw device driver is obsolete and we should not add it to the
s390 kconfig. I know that it is needed in SLES10 for compatability to
SLES9 but given that the option is supposed to vanish I prefer to keep
it out of the upstream tree.
