What problems did you have?  That patch should apply cleanly, or, at least,
it has for me.

I don't know what the second controler is, but you're getting all drives in
PIO mode.  :(  I have the same problem on my PIIX3 controllers when running
with the IDE patch, but I haven't had time to talk to the authors.  My
suspicion is that your kernel didn't get everything patched correctly.  If
you can send the output from that patch command, or try downloading it again
(note: download using lynx and 'print' to a file does NOT work).

You should not use RAID5 on IDE if you want to be able to run in
degraded mode.  If you have a failed Master disk, both (Master and
Slave) disks on this controller are inaccessible and your RAID
array is unusable.  I had a IDE-Master HD failure last week,
my IDE-Slave ATAPI ZipDrive was not found by OSs, I will try next
week with this HD as Slave.
