Well, I found a pre15 driver which I've applied to a 2.0.35 kernel
under Slakware. So far, so good, thanks!
Prior to applying pre15, I was using pre8. While that release was
stable enough, I did have one interesting problem which I'm not sure is
unique to this driver. I have a lowly x3 CDROM drive (NEC). A friend
brought over a CD-ROM that was apparently created with a x4 CDROM writer
(I found this out later). The drive tried for about 20 seconds to try
and read it, ultimately failing. I didn't notice this, however, and
tried to mount the cdrom anyways. The moung command hung, and the
system stop responding to disk I/O requests very shortly there after and
I had to reboot the hard way (reset button). Here's an excerpt from my
kernel log:

Sep 30 23:46:25 gremlin kernel: Disc change detected.
Sep 30 23:46:25 gremlin kernel: VFS: Disk change detected on device 0b:00
Sep 30 23:46:55 gremlin kernel: scsi : aborting command due to timeout : pid 70410, scsi0, channel 0, id 2, lun 0 Read (6) 00 00 10 01 00
Sep 30 23:46:55 gremlin kernel: SCSI host 0 abort (pid 70410) timed out - resetting
Sep 30 23:46:55 gremlin kernel: SCSI bus is being reset for host 0 channel 0.
Sep 30 23:47:02 gremlin kernel: SCSI host 0 abort (pid 70410) timed out - resetting
Sep 30 23:47:02 gremlin kernel: SCSI bus is being reset for host 0 channel 0.
Sep 30 23:47:02 gremlin kernel: SCSI host 0 channel 0 reset (pid 70410) timed out - trying harder
Sep 30 23:47:02 gremlin kernel: SCSI bus is being reset for host 0 channel 0.
Sep 30 23:47:02 gremlin kernel: SCSI host 0 reset (pid 70410) timed out again -
Sep 30 23:47:02 gremlin kernel: probably an unrecoverable SCSI bus or device hang.
Sep 30 23:47:02 gremlin kernel: (scsi0:0:0:0) Synchronous at 10.0 Mbyte/sec, offset 15.

I'll give this a try with the pre15 driver (when I can afford the time
for the fsck's afterwards ;-(
