Are you sure the libata core can't see this ide controller and connect
to it?  That way you would use the scsi system if you do that and you
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.

What is the issue here? This is no different than what is done in other
Virtualization platforms. For instance, the Xen blkfront driver is no
different - if you specify the block device to be presented to the guest
as an ide device, it will register for the appropriate ide major number.

I'm pretty sure I already complained about
this in a previous review round.
