In this case I kept the old comments, as I wasn't sure that they were
incorrect. I will have a go at rehashing this paragraph.

It is true that I have never needed it for either of the Ultra 100's I have,
although having it enabled didn't seem to hurt.

As above, this is duplicated from the original help. So I'm not making things
worse. That said I am hoping to make things better.
I will change it to make it clearer that the statements about Ultra33 are
specific to Ultra33.
Are you telling me that I should change it to be unlimied # cards?

OOps... will fix.

I will: I hadn't noticed it. [ looks ] So there is another patch for the
(ugh!) 'special feature' -- do you want me to:
- integrate that patch with mine & resubmit
- take input from that patch into mine & resubmit
- go away :-(
Does ataraid work well on 2.4? I have never used it as I have preferred the
user-space tools available for Linux-raid. On 2.5 KConfig as ataraid doesn't
work I guess the right thing is to always configure as non-raid, so not
requiring a user-question and therefore no help.
I have updated my Configure.help patch in ways that I hope address your
concerns above. I can see from Steven Drake's patch that I should also modify
Config.in: should we continue I will do that & send a patch for it.
If we come to consensus on this patch I will update Steven's KConfig one also.
