[PATCH] ide: ide-generic, allow for capture of other unsupported devices 

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.
