[PATCH] 2.5.13 IDE 53

 - Start splitting the functions for host chip handling in to separate entities.
   This change is quite sensitive and may cause some trouble but it's for
   certain worth it anyway, because it should for example provide a much better
   infrastructure for th handling of different architectures.
