You don't need to do that. At least I haven't ever needed to do that.
Just get the latest package and install it. Well it's mandrake so ...

sane-backends doesn't know anything about harddrake and couldn't care

I don't know these details but I'm surprised that they need a specific
version of sane-backends.

I have never heard that anything from sane-backends does this. So I
think it's one of the Mandrake tools.

The package "libsane" seems to be an invention of distributors. I know
that debian has the source package "sane-backends" and binary package
"libsane" (the SANE libraries) and "sane-utils" (e.g. scanimage).
Maybe it's similar with Mandrake?
Most of your questions are better suited in a Mandrake forum as they
aren't really related to SANE itsself but the packages created by

sane-backends supports libusb since quite some time. And it was needed
before kernel 2.6 at least for some scanners. So I'd be surprised if
the Mandrake version had no libusb support.
You can check by running "sane-find-scanner -v -v". It should print
messages about using libusb.
