I am very sorry for this inaccurate information. As it turns out, only the GENERIC kernel is bootable, my custom configuration doesn't. On the bright side, this indicates some feature missing from my normally very lean kernels, nothing is kaputt beyond repair. I'll just have to find out which module just has to be in the kernel to make it boot from an USB stick. -c
