There are three issues here that need to be addressed.
1) megaraid_mbox doesn't currently handle all of Chris's hardware.
   It's missing some PCI IDs which it should be able to handle.
   101e:1960 101e:0475, aka PCI_VENDOR_ID_AMI, PCI_DEVICE_ID_AMI_MEGARAID3
			    PCI_DEVICE_ID_AMI, PCI_SUBSYS_ID_PERC3_SC 

2) megaraid_mbox doesn't handle other sets of hardware it should be
   able to handle (Dell PERC2/{SC,DC}).  I am not sure why.

3) no megaraid_ioport driver has ever been produced, which was the
   original reason for splitting megaraid_mm and megaraid_mbox.  This
   driver is necessary for Chris's other older hardware.
   PCI 101e:9010, aka PCI_VENDOR_ID_AMI, PCI_DEVICE_ID_MEGARAID


Thanks,
Matt
