Are you sure the libata core can't see this ide controller and connect

would need a much smaller ide driver, perhaps being able to merge it
with your scsi driver.

We really don't want to write new IDE drivers anymore that don't use
libata.

The blkvsc driver isn't an IDE driver, although it currently claims
the old IDE drivers major numbers, which is a no-no and can't work
in most usual setups.  I'm pretty sure I already complained about
this in a previous review round.
