This option was removed from kernel in 2.6.12, but there is a new possibility for computers with short 40 wire
IDE cables to have UDMA100.
One could add it to the array of such devices. Here is the patch I use for 2.6.26:

{ 0, }
AFAIK it will be included in next kernel version (2.6.28 ?).
Therefore I changed the bug severity to wishlist.
Should it be reassigned to a more recent linux-source version?
Feel free to close it if it is included into kernel.
Bye,
Erik
