ACK, thanks for your report. In fact, just 2 weeks back Philipp Kern (in CC) has added some fixes in this exact area in debian-cd git. He's moved the root.bin up to 0x01000000 (16MB); I'd be happy to move it up to 0x02000000 as you suggest. Phil - what do you think? I'm also going to make sure the fixes are backported to our stable build tree for the next point release. -- Steve McIntyre, Cambridge, UK.
