Cool! Does this work with the VFAT emulation layer?

In theory I think it should. I haven't tested it though.

At least partial transfers are broken, the command returns zero data.

Could you elaborate a bit more please? I've no idea what you mean by "partial 
transfers".

Actually the problem was that Qemu block devices use fixed sector size 512, 
not variable 2048/512 like scsi layer. This meant that the bdrv_read 
transferred too little data. Fix attached.

Ah, I see. I'm fairly sure your patch is not sufficient though. I'll look into 
it.
