IPMI sensors for Linux 2.6.24

I couldn’t find ipmisensors module for 2.6.24 kernel, so I tried to port ipmisensors-20060805-0622.diff. After a bit of hacking and guesswork I managed to modify it that it compiles cleanly on Linux kernel 2.6.24 from Ubuntu 8.04.2 (2.6.24-23.48).

The diff is here:
http://tomasz.sterna.tv/stuff/Linux/ipmisensors-20090209-0624.diff

But after loading the ipmisensors module:
# lsmod | grep ipmi
ipmi_poweroff 10540 0
ipmi_watchdog 20820 0
ipmi_devintf 10248 0
ipmisensors 19592 0
ipmi_si 43788 2
ipmi_msghandler 39384 5 ipmi_poweroff,ipmi_watchdog,ipmi_devintf,ipmisensors,ipmi_si

I still get no sensors:
# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.

There are some sensors on BMC:
# ipmitool -I open sdr list

Fan 2 | 11 unspecified | nc
Fan 3 | 11 unspecified | nc
Fan 4 | 11 unspecified | nc

CIOBE 1.2V | 1.23 Volts | ok
CIOBE 2.5V | 2.58 Volts | ok
BIOS Progress | disabled | ns
Watchdog | disabled | ns

There is a problem in dmesg, but being unfamiliar with the IPMI itself, I unable to find out whether I did screw up the port, or there is a deeper problem:

You are free to try the patch and see whether it works for you. Or if you could fix the problem, I would be very glad.
