No. On-disk disklabel(8) is completely machine dependent.

Possible Workarounds:

(1) check partition offset/size on i386 and use dkctl(8) addwedge on macppc
(2) print disklabel on i386, and use patched disklabel(8) that can update
    in-core label only with -R (read label from protofile) option

(3) implement BSDDISKLABEL_EI as sys/arch/sh3/sh3/disksubr.c

etc?
