Yeah, was thinking about it when Cedric sent out this patch, but since 
theoretically the witherspoon128-bmc model could be used with a swift 
image, I put it to the side. But now that you mention it, yeah we can 
add the SD/MMC to it later so that'd be valuable to have in a qemu 
model. Will send a patch based on the 128 for a new swift bmc to start 
with.
