Perhaps I may say: yes please!

As an ignorant newbie, myself I'd vote we at least apply the patch:

If that's not reality, I need more education.

If that is reality, but not what we want to say, then we can balance the
work involved in updating ide-scsi vs. the likely pain of answering all
the later newbies who come here saying I swapped 2.6 into my Red Hat/
etc. 2.4/ 2.5 and life went downhill from there.

Myself I gathered 2.6 experience without ide-scsi only by luck.  I have
a usb drive and an atapi drive, I had to choose one or the other to
begin with, I happened to choose the usb drive, and I happened to
dislike the idea of overriding a kernel default.

I'm no longer sure I remember exactly how I fell back into trying
hdc=ide-scsi.  I know I'm contact with other newbies who take more the
attitude of learning to change as little as possible in how Red Hat
boots, rather than the attitude of learning how to survive with as
little from Red Hat as practical.
