With that, usefdt=1 is confirmed working on PowerMac 11,2 (like the quad core). You must use vt, not sc, but everything should work out of the box once that patch is in.

I can tell you that 341705 requires kern.smp.disabled=1 and usefdt=1 in order to boot without a strange freeze or panic. I will check out 341781 now and see what new stability has arrived but 341705 requires hand holding and small prayers at boot time. Yes the bge0 and bge1 do swap places. I see your notes on Bug 233863 and will follow along here. Dennis
