fs'es are mounted from block devices, and /dev/hdc is as much block device as /dev/hdc1. Just like a floppy - they don't have partition tables either.
Booting off such a thing will work too, if the bios don't make assumptions about partitioning. They used not to, last time I looked the pc bios simply executes the first sector of the disk and the code there have do support partitions itself if necessary.
I see no need to partition such a beast into a single big partition - you just loose a sector to the partition table.
