I have a live sparc64 box, however it's currently in a pile of dead sparc32 and 64 boxen, and hasn't been booted for a long time. So it's not exactly accessible - that and I've lost my last real serial port so I can't actually talk to it anymore. (and the expresscard one I obtained for my laptop doesn't work properly for some reason - fricking cheap serial chipsets) I'll have a go at making it work soon, and see if I can get this going. In the mean time, I'll send that patch and anything else I've got that looks promising.
