SubjectRe: [patch] I-Opener fix (again)

Basically if the setting of

* "hdx=flash" : allows for more than one ata_flash disk to be
* registered. In most cases, only one device
* will be present.

fails then I will look into this but, the breaking of laptops that have
CFA devices that do not come on channels in a pair canb not happen.
If you have a vender unique setting that will follow always the way
I-Opener's are setup then that is better.

Cheers,
