This is one of those systems that has some 150K of dmesg on boot due to that pesky USB barfing - IRQ XX nobody cared!.

Due to it's size I haven't included it here. Here's a link to it however - http://blue-labs.org/~david/dmesg.out.2.5.70.bz2

(There are a lot of unknown devices in lspci output, if an interested party wants, I'll provide as much detail as I can.)
