Trouble with LSI SAS1078

[Slawa Olhovchenkov]

I found PR kern/134520 and discursion in -scsi at 2010-05-01.
I have same trouble for 9.0-RELEASE and Intel SR2600URLXR.

Matthew Jacob (currently not working on mpt) wrote "I have this
chassis and it seems to work okay for me".

I think difference in AXXRAKSAS2 -- working system have full RAID
support, system with "unable to map registers in PIO mode" -- lost
RAID support.

Can somebody modify driver for support this configuration?
