Fiasco reserved memory area overlapping with bootloader area

[Christian Prochaska]

Hello,

I recently had the problem that a physical memory area reserved for 
Fiasco overlapped with a Bootloader area, resulting in one or possibly 
more corrupted boot modules. Apparently there was not enough physical 
memory available, but i would suggest that in this case Fiasco would 
print an error message and stop as soon as it knows about the overlap 
instead of further executing the corrupted modules.
