     libata/IDE: remove combined mode quirk
You can't just remove the "combined_mode=" kernel parameter or
every Linux user who uses that will get an unbootable kernel
with no good way of diagnosing the problem. It should still
be accepted and just print a warning.

No, most modern distros will simply Just Work(tm) due to mount by label, udev, and similar gadgets.

As long as you have at least one (if not both) ATA drivers, you have a kernel that will boot your hardware. And by definition those using combined_mode= do indeed have the necessary drivers.

Please don't do this!

Yeah the kernel will boot but the hd performance is sh*t on my laptop. I am running FC6 with kernel 2.6.21 and without the combined_mode setting my disk performance goes down to a whopping 1.25mb/sec from 44mb/sec when I boot with combined_mode=libata. It make my
system unusable!
