Hmm, we're not using any graphics adapters with PowerPC right now.

In addition to that, I also need a testcase to actually exercise the code... :) -- Hollis Blanchard IBM Linux Technology Center -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
