Bug#612376: flash-kernel: please include efikamx support



Package: flash-kernel
Version: 2.37

The attached file is part of the flash-kernel 2.28ubuntu10genesi1
distributed by Genesi.

Please incorporate the efikamx_flash_kernel function.
I would change the boot.scr generation to include
console=${console} as part of bootargs.
