I just now tried out *only* "the other SCSI suspend patch", and by itself it hangs on resume. Laptop computer, blank screen, no serial ports, no printk()s visible.
And there's one minor bug in that patch: it uses GFP_KERNEL to alloc a buffer, but on resume it really should use GFP_ATOMIC instead, since the swap device is the same drive we're trying to resume..

That's probably why it hangs when used as-is by itself. I may do some further testing.
