I've had some partition/slice issues in the past w/ install CD and missing device entries with non-standard slice (anything except s1 entry), can't recall details, but running sysinstall w/ newfs flag to N creates appropriate entries. Else I've found suitable device entries elsewhere or make them temporarily with mknod.
