I've worked with Eric offline to resolve the issue we had and get some
more changes in, but he has left for his vacation today.  He send me
a patch though and left it to me whether we'd merged it despite only
moderate testing.  Given 2.6.7 was just done and he'll certainly be
back before 2.6.8 I'd go for it.  Below is the patch rediffed against
scsi-misc-2.6:
