Well, do you need a feedback? :-)

I have the same problem on my home machine (Pentium 133).  I have only a
master CD-ROM on wdc1, and I think it is jumpered correctly.  The ratio
found/not found was about 1:8;  when I put IDE_DELAY=22000, the ratio
became 1:4, just like in the original report.

So it's still there, in 3.2-stable (as of June, 14th or so).

I can provide verbose dmesg output tomorrow if someone thinks it might
be of any interest.
