So you have more RAM than I do :) -NX (Execute Disable) protection: active You enabled PAE, I didn't.. (Though I have tried both, makes no difference) DMI present. +Using APIC driver default Hmm.

So most of the differences seem to be BIOS/firmware rather than hardware. The PCI bus layout is identical for eg. Looking at your .config, I notice that you don't have CONFIG_FB_BACKLIGHT set (because you don't have any framebuffer drivers that use it enabled). Can you enable say.. CONFIG_FB_RADEON=m and CONFIG_FB_RADEON_BACKLIGHT=y (which should turn on CONFIG_FB_BACKLIGHT=y by dependancy), and see if it stops working for you? (You don't even need to load radeonfb.ko, just have it compiled).
