I'll have to look into U-Boot and see if something is accidentally using page 0 for something, or perhaps the kernel is just using that as the first free page... > Hey, do you know what's going on with merging code?

Lee would merge any SoC core patches (i.e. arch/arm/mach-bcm2835), and relevant maintainers own the graphics and cpufreq drivers.
