I tried this, with partitions a at offset 64, c and d at offset 0, d
marked RAID, and then raid0a at offset 0 (which thus becomes 64).
Looked great, until I tried to boot it.  Non-bootable disk.  It seems
that the boot sector got installed at the start of partition a,
instead of at the start of the disk...?  "fdisk /dev/rsd1a" showed the
bootable partition in place, while "fdisk /dev/rsd1d" showed nothing.

Any hints?  Should I have used partition e instead of d, i.e. can it
be that the "specialness" of d is what bit me?  When you say offset 0,
do you mean from the physical start of the disk, or from the start of
partition c, normally at 63?
