Most (all?) linux filesystems work just fine against raw devices. They are simply unaware of the difference. The larger problem is firmware trying to find partition tables/etc in the middle of a filesytem, but even then its mostly a non issue because random data doesn't tend to look like partition tables or MBRs.
