Yeah ... that's what I reckon too ... but Ollie's part of (if not all of) the DoC

Initial program loader ... there's a bunch of us @ linuxBIOS taking these things

broken :-(

If you want me to try things and send you results, I'm cool with that.  I'd *rather* be 
writing to the block device (at least you should be able to "sync" it).
