Hi Olivia,
The current implementation only supports ppc64 architecture. Either the current driver needs to be extended for ppc 32 bit too, or new handler functions need to be implemented for 32 bit PowerPC.
I do not have a 32 bit PowerPC system to try this.

Patches are welcome, and I will be happy to help with reviews :-)
