Here's my solution to the problem:
I made a partitioen above cyl 1023 using PartitionMagick and realized I
needed to change the partition ID to A6. Couldn't to it with PM or OpenBSD's
fdisk, so I downloaded RedHat's boot and rescue disk, used that fdisk to
change the ID. Finally, I made a disklable and ran newfs in OpenBSD and now
everything works just fine.
You could probably do the whole thing with RedHat's fdisk, but wouldn't it
be nicer if OpenBSD's fdisk didn't have these limitations?
