Subject: [PATCH] cciss: add some older controllers to the kdump blacklist

Some other older controllers also do have problems to perform a kdump.
Adding controllers to this list means that the driver will signal
this non-ability via a resettable flag correctly. 
The unsupported list was created after a consultation with HP.
