The problem is that the low-level APUS kernel code
differes a bit from the "standard" kernels. Only minor
modifications should be necessary to get MOL working, but
it definitely takes someone with assembly knowledge
(and access to an APUS machine).
If I remember right, the main problem is a "dynamic" kernelbase.
