qemu assumes it's loading a raw binary kernel zImage. Currently it is loaded 
at 0x10000. The linux kernel don't care where they are loaded, so this may 
change in the future.
If you configure u-boot for a base address of 0x1000 it will probably work.

Qemu emulates and ARM Integrator/CP baseboard and CM/926 or CM/1026 core 
module. Full documentation is available from http://www.arm.com/
