The ide-generic driver gives you DMA at bios tuned speed so can actually run a
lot of unsupported devices quite well.  It has a pci table so that it doesn't
grab disks owned by other drivers but no way to override this.  The patch adds
an option ide-generic-all which makes the driver grab everything going that is
IDE class.

The diff is messy because I put the special case as case 0 to make the if
conditional and long term maintenance easier.

This has been in Fedora for some time.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
