#3 Using the system information structure

[Ronald Landheer-Cieslak]

The boot loader/bootstrap code passes a system
information structure to the kernel_main() function. We
should probably do some interpretation of that
structure and store the relevant information in some
easily accessible location - either that or pass the
relevant parts of the information as parameters to the
module's initialization code (e.g. mm_init() will have
to know how much memory there is...)
