The different firmware versions return different PCI-IDs, so that
the right driver attaches, e.g.:

mpii.c: { PCI_VENDOR_SYMBIOS,   PCI_PRODUCT_SYMBIOS_SAS3008 },
mfii.c: { PCI_VENDOR_SYMBIOS,   PCI_PRODUCT_SYMBIOS_MEGARAID_3008,

PCI_PRODUCT_SYMBIOS_SAS3008 = 0x0097
PCI_PRODUCT_SYMBIOS_MEGARAID_3008 = 0x005f

There is a PERC H330 and a PERC HBA330 and the Dell PERC9 user manual
(includes the H330) says you can boot it in HBA mode. Not sure if
that means that you can chose the firmware.

-> This is attaching a H330 (RAID version) and it gets the mfii driver.
