Some formats can be erroneously identified by the check code if you don't get the ordering right (the case I know about, MSDOS partitions vs. Atari TOS/GEM partitions, hinges on a particular checksum being calculated in the atari code). I've moved the msdos checker to the bottom of the list more often than I can keep track of... If sysv68 cannot be confused with any other format, no harm done by enabling it by default. Otherwise, things may get interesting.

No, the PPC based Motorola MVME boards use the (currently not supported by linux) AIX partition tables, as do also the motorola powerstack machines. The m88k based Motorola MVME boards use the sysV68 partition tables, but m88k is not yet supported by linux. Incidentally, what is the problem you have with SYSV68_PARTITION ?
