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? -- Matt Sealey Manager, Genesi, Developer Relations
