Version 2 looks much better - thanks.

The use of ? 1 : 0; here is redundant.

I did not see this addressed in the changelog?


                                drive->dev_flags &= ~IDE_DFLAG_PRESENT;

You have a nice set of inlines to facilitate testing bits,
but not for the above use?
I guess this was not worth the abstraction for now.
