Here's what went into ide in 3.17:

$ git log -p v3.16..v3.17 drivers/ide/ 
commit a53dae49b2fea43d8f4ec5aeca0e288bbc8d6895

    ide: use module_platform_driver()

    Eliminate boilerplate code by using module_platform_driver().

...

and that driver doesn't have anything to do with zip drives.

So problem is either somewhere else in the kernel or maybe something's
missing from the 3.17 config or somewhere completely different.

You could bisect the kernels between 3.16 and 3.17 - unless someone has
a better idea...
