Garet,
You are wasting electons, the interface is gone and the API to the
transport is wrecked. I will need to compose a loadable module to renable
the support. Clearly 2.5/2.6 is not friendly with the needs of the
industry and it will never be at this rate.
In the end, I will end up writing a closed ATA binary driver for sale as a
replacement. I have had several requests to consider the option. As much
as I do not like the idea, it is less offensive than the current
direction.

Do not worry Garet, I will reimplement it later in 2.5.
I need some free time to do it, (maybe next month?).

The 2.5 code is rather in flux, various things are changing including
redoing generalised ide/scsi generic command access to be a lot more
consistent that ioctl back doors.
I wouldnt worry about it just yet
