No, I personally myself had the hardware. Really.

Note that in general hoping that current mainline kernel will
always work with ancient QEMU is a losing proposition -- it is
always possible that a kernel improvement will trigger a latent
model bug in QEMU. (To pick a random example, some while ago fixes
to how the kernel dealt with BGR and RGB pixel formats on the
versatile board broke QEMU because we weren't modelling it right;
that was just a QEMU bug for which the fix is "get a newer QEMU".)

The back-compat in the PCI code is so that the older kernels (2.6.x)
will continue to work, which is not quite the same thing.
