The interface that I am interested in overriding is the requestProbe
function on the IOPartition(*)PartitionScheme IOStorage classes.

More testing has shown (so far) that IOUserClient has changed between
Tiger and Leopard. kextload indicates that this change is not backwards
compatible. However, the change to IOUserClient is not required for my kext.

So I actually have a more complicated situation. I would like to have a
kext that works on both Leopard and Tiger, with some of the kext classes
compiled with Leopard interfaces and some compiled with Tiger
interfaces. I'm not sure how to go about combining two targets into one kext.

I have not done enough testing yet, but I am hopeful that the
requestProbe interface is backwards compatible because it does not use
one of the reserved virtual function locations.
