[BISECTED] ipmi_si not loading since 2.6.39

I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39
module loading ends with following message:

ipmi_si: Interface detection failed

Then ipmitool is unable to control IPMI device.

Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.

I got this bisected to following commit:

ipmi: convert OF driver to platform driver

of_bus is deprecated in favor of the plain platform bus. This patch
merges the ipmi OF driver with the existing platform driver.

CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF.

Compile tested with and without CONFIG_OF. Tested OF probe and
default probe cases.

I wonder whether this is a bug, or I'm doing something wrong?

Thanks in advance!

with best regards
