[lm-sensors] IPMI sysfs support for 2.6.16.x

[paul@astropaul.com (Paul Reilly)]

Hello,
I am trying to get IPMI Sensors working on kernel 2.6.16.33.
I have a PenguinComputing Altus Server with inbuilt BMC, and lm-sensors
suggests I need bmcsensors. Googling I followed the instructions here:
http://bmcsensors-26.sourceforge.net/

It appears I need to do 2 things:

(A) patch my kernel for ipmi sysfs support
(B) patch my kernel again with the IPMI sensors patch

I would love to just use 2.6.17 and skip (A), but I am required to
use 2.6.16.33 kernel only. So:

Doing (A) works so far. The patchfile contains patches for 8 files, and
worked for all except the file "ipmi_si_intf.c" which failed on several chunks:

patching file drivers/char/ipmi/ipmi_si_intf.c
Hunk #1 succeeded at 110 with fuzz 2 (offset -2 lines).
Hunk #2 succeeded at 196 (offset -5 lines).
Hunk #3 FAILED at 984.
Hunk #4 succeeded at 1183 with fuzz 2 (offset 19 lines).
Hunk #5 succeeded at 1331 with fuzz 2 (offset 59 lines).
Hunk #6 FAILED at 1915.
Hunk #7 succeeded at 1929 with fuzz 1 (offset 31 lines).
Hunk #8 succeeded at 1972 (offset 31 lines).
Hunk #9 succeeded at 1985 (offset 31 lines).
Hunk #10 FAILED at 2088.
Hunk #11 FAILED at 2167.
Hunk #12 succeeded at 2329 (offset -26 lines).
Hunk #13 FAILED at 2422.
Hunk #14 succeeded at 2431 with fuzz 1 (offset -31 lines).
Hunk #15 succeeded at 2552 with fuzz 1 (offset -36 lines).
Hunk #16 FAILED at 2574.
6 out of 16 hunks FAILED -- saving rejects to file
drivers/char/ipmi/ipmi_si_intf.c.rej

I tried patching manually, but it was beyond me. For example chunk 3
refers to static LIST_HEAD(smi_infos);  which is not present in my 2.6.16.33 
ipmi_si_intf.c

How can I tell which 2.6.16.X  branch these patches are meant for?
Perhaps they apply on an earlier or later 2.6.16.x series kernel.

Can I just copy the whole drivers/char/ipmi/  dir from a 2.6.17 kernel,
and put it in my 2.6.16.33 ?

Thanks,

Paul
