For the intended audience, yes.

Who is talking about ISA? All cards we had in mind are PCI. Of course you have to do the usual initialization work in your probe/release or init/exit functions. These are just a few lines you find in any beginners device-driver-writing book. I don't think that the UIO framework could simplify that in a sensible way.
