Interesting!  Apparently the vendor+product ID is not enough in this
case.  The subvendor and subproduct ID are interesting too.  Yes, I
had got the NetRAID case wrong, since I thought the following
was the main vendor+product IDs:

vendor HP		0x103c	Hewlett-Packard
product HP NETRAID_4M	0x10c2	NetRaid-4M

However, your RAID controller has these:

vendor DEC		0x1011	DEC
product DEC CPQ42XX	0x0046	Compaq SMART RAID 42xx

To, that one looked like it is matched by the cac driver (Compaq array
controller).  However, watching closer I now see that the sub-identifiers
are excluding your controller.  Then looking around I see that it is
really in the subidentifier field the above HP identiiers should go.
I'll cook up a patch for you tor try, stay tuned.
