plain 2.2.X: no ide CD-RW?

For a while now, I've been running a 2.4 kernel, but (for my research)
I need to now run a 2.2 kernel.  I was hoping to just run a stock
2.2.19, but I've found that I can't use my CD-RW drive, either as a
plain IDE cdrom, or as a scsi-emulated one.  (I have ide-scsi, ide-cd,
and scsi all as modules.)

When I try things as scsi-emulated CD-ROM, I get the following:

  Jun 22 19:58:15 lydia kernel: ide-scsi: The scsi wants to send us
     more data than expected - discarding data
  Jun 22 19:58:16 lydia last message repeated 83 times

Instead, if I try ide-cd, I get these messages:

  Jun 22 20:11:38 lydia kernel: hdc: status error: status=0x58 {
     DriveReady SeekComplete DataRequest }
  Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command
  Jun 22 20:11:38 lydia kernel: hdc: status timeout: status=0xd0 { Busy }
  Jun 22 20:11:38 lydia kernel: hdc: DMA disabled
  Jun 22 20:11:38 lydia kernel: hdc: drive not ready for command
  Jun 22 20:11:38 lydia kernel: hdc: ATAPI reset complete
  Jun 22 20:11:48 lydia kernel: hdc: irq timeout: status=0x80 { Busy }
  Jun 22 20:11:48 lydia kernel: hdc: ATAPI reset complete
  Jun 22 20:11:59 lydia kernel: hdc: irq timeout: status=0x80 { Busy }
  Jun 22 20:11:59 lydia kernel: end_request: I/O error, dev 16:00
     (hdc), sector 64
  Jun 22 20:11:59 lydia kernel: hdc: status timeout: status=0x80 { Busy }
  Jun 22 20:11:59 lydia kernel: hdc: drive not ready for command

I have these problems with 2.2.1[7-9] & 2.2.20pre5.  However, if I add
one of the IDE patches, all is well.  2.4 kernels have never given me
these sorts of problems.

I have a 440LX motherboard (HP Pavilion 8260), hooked up to a Plextor
PX-W8432T 4/8/32 CD-RW, attached as /dev/hdc.  I also have an OnStream
DI-30 as /dev/hdd, and a Maxtor 91020D6 10G drive as /dev/hda.

I can live with just running an ide-patched kernel, but it seems very
odd that I can't even use the drive as an IDE CD-ROM drive with a
stock 2.2 kernel.  Is this a bug, or a limitation?  I'd be happy to
perform any tests to try and track this problem down.

Thanks!
