The patch just went it Linus' BK tree.
It is below.
I don't promise that this fixes everything, just that if fixes the

Remove BUG in md.c that change in 2.5.33 triggers.
Since 2.5.33, the blk_dev[].queue is called without
the device open, so md_queue_proc can no-longer assume
that the device is open.
