[BISECTED] ipmi_si not loading since 2.6.39

Hello,

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:

commit a1e9c9dd3383e6a1a762464ad604b1081774dbda

    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

nik
