First of all: It is VERY likely that we will support a new dump format
in the near future. Believe me.

Second, how should that work? The callback has an integer and a void
pointer. The integer is currently used to specify the CPU number. The
void pointer is used to hold the ELF note information. How the hell can
I code the information for a new dump format. Or am I missing something?
