Last time I looked the only thing the i386 'c' partition was used for was to protect the labelsector. It wasn't possible to access the disk through it!
On NetBSD/i386, if you mark the "c" partition as "unused" in the disklabel, then you can't access the disk through the "c" partition (you get ENXIO "Device not configured"), but if you mark it "unknown" in the disklabel then you can access the disk.
