The aacraid cards, which uses hba_monitor_version, hba_kernel_version
and hba_bios_version for each piece does not fit into the single
'firmware revision' common ideal and were noticeably missing from this
patch set.

Fortunately (?), Adaptec has not bought into using sysfs for their
management applications to pull these pieces and continues to pick them
up directly by issuing ioctl pass-through calls to the card's firmware,
so we have some leeway to change them to mold to a developing standard.
The fact that sysfs is a developing standard will confirm the management
application folks reasoning for shying away from sysfs ;-/
