[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.
