On a new world Mac? I'm thinking a mistake has been made. Maybe you mean via-pmu? According to FreeBSD's website all Macintoshes with a built-in USB port are supported. This would only mean new world Macs and they only have a via-pmu - no cuda device. > Mark, is your complete qemu patch available somewhere?
