I hadn't thought of that, will try it out later.

Wait, let me get this straight: you want to set probe_mask to 0x0 as a default,
which skips probing of the primary and secondary ports, and to do the checking
whether the IDE PCI controller uses legacy iobases only when the user has
enforced it by setting probe_mask to 0x3? At least this is how i understand
it...
