Thanks. Is the upstream support for this in QEMU now?
Not yet, but it should be in 2.6.

It should work on real hardware; the submission of requests works more or less the same as for a full-blown driver. I wouldn't have problems with adding the dependency though, since real hardware would come with an option ROM.
This I might be able to test directly on real hardware. Certain systems cannot use the LSI option ROM (coreboot-based systems in particular), so I am keen on seeing this work outside of QEMU.
I will test and report back, though it may be a few days before I can do that.
