Can we make this 0x200 for the size? That's what kvmtool uses and, from the virtio-mmio spec, config data from offset 0x100+ is driver-specific. A quick look at the virtio block driver suggests we only use 31 bytes of that at the moment, so 4k is really OTT (and doesn't match the page size for 64K page systems anyway).
With that change:

Sure, I'll send a patch to make this change for the foundation model too.
