I assume you have tested this on an actual pmac, as well as qemu?
I tested the patched driver and its console functionality using Zilog SCC hardware in a Mac IIci, as well as QEMU's q800 virtual machine. That should suffice from a code coverage point-of-view, since pmz_receive_chars() is portable and independent of CONFIG_PPC_PMAC. Moreover, I don't know how to get my PowerMac G3 to execute the kludge that's to be removed here. I can't prove it's impossible, though.
