Sorry, I was referring to the backport of the 2.4 IDE code to 2.2.
I'm currently using ide.2.2.19.05042001 successfully, which I got from:

ftp://ftp.us.kernel.org:/pub/linux/kernel/people/hedrick/ide-2.2.19

I've used several similar patches, though. Stock 2.4 kernels work
fine with my CD-RW as well; however, I've now discovered that plain
2.2 kernels do not. This could easily be a long-standing problem,
probably at least a year old - I've only recently stumbled across it,
though.

Since I have a solution (use the 2.4 IDE backport), this isn't
critical; however, since many people still rely on 2.2, and I'd like
to use a stock 2.2 kernel if possible, I'm willing to spend some time
debugging this.

Thanks!

(A bit of background: Before I got my CD-RW drive last summer, I
bought an OnStream DI-30 drive. This drive was then only supported on
2.2 with the 2.4 IDE backport, and so I've used this drive
successfully with 2.2.16 + 2.4 IDE patch, and a similar combination
since. Since stock 2.2.19+ now support this drive through the osst
patch, I thought I'd try it out. It does work, but at the cost of
losing my CD-RW.)
