Don't think so (you're referring to Jeff's git-sas-jg.patch?).  It dies
with current -linus tree.


drivers/scsi/sd.c: In function `sd_read_capacity':
drivers/scsi/sd.c:1301: internal error--unrecognizable insn:
(insn 1274 1273 1797 (parallel[ 
            (set (reg:SI 0 %eax)

                    [

                    ]  ("drivers/scsi/sd.c") 1282))
            (set (reg:SI 1 %edx)

                    [ 
                        (asm_input:DI ("A"))
                    ]  ("drivers/scsi/sd.c") 1282))
        ] ) -1 (insn_list 1269 (nil))
    (nil))

It'll be workable aroundable of course, but it's a hassle.
