Card detect you should be able to handle on the board level without
waiting for QOMification -- it's just modelled as a QEMU irq line
(the vexpress board connects it up to a random register, or you could
not connect it to anything, etc).
I'm working on the QOMification of sd.c this week, though I'm very
rusty on how to properly model buses.
