2.4.22-pre3 : SoundBlaster IDE interface missing

[Ben Castricum]

I have one of those ancients ISA-PNP SoundBlaster cards with an additional
IDE interface on it. It all worked perfectly up till 2.4.22-pre2 but with
pre3 the IDE interface is no longer detected.

Any help on getting it to work again would be great.
