There is a slight chance that thing would be compatible with
the MCA ESDI, maybe :)

And what about using e.g. disktype DTYPE_ESDIMCA for the PS/2 ESDI
disk?

If that is not the right thing, it would probably be okay to go
just with the simple check (i.e.  DTYPE_ESDI on PS/2 --> claim it's
ed(4)), at least until 'wd* at mca?' would be supported. I'd rather
avoid adding unnecessary bloat to bootblocks until then.
