One thing I'm curious about, has anyone EVER made a system which
actually used the 36-bit addressing on the G4?

I always wondered why such support was never in Linux but then
again if nobody connected the other 4 address lines on any PowerPC
board ever made that ran Linux, there's nothing ever to test it
on anyway. It wouldn't be any more problematic (same way as the NX
bit..) than Intel PAE support, right?
