Linux 2.1.128 & ide-cd's that aren't ATAPI compliant..

Just spent last night trying to get 2.1.128 running on my home system,
and noticed that my Wearne's 32x IDE cdrom drive does not work at all.
(it does work under 2.0.35).

In looking deeper, I found that the drive was sending a 'UNIT ATTENTION'
code back whenever the PAGE_CAPABILITIES was requested. Now, the ide-cd
would silently fail when it couldn't get this page (instead of
complaining, saying you have a ide cdrom drive that fails
page_capabilities)

I'm trying to figure out what the heck is wrong with the drive (any
clues? and linux programs that can probe this sucker?)

But, I think ide-cd shouldn't fail silently when the drive isn't ATAPI
compliant; it should complain LOUDLY, or put a set of default values
(like 2.0.xx does) in place. (otherwise, we will be seeing a multitude
of questions about why my ide-cdrom drive doesn't work..)

Any clues?
