The ALF that ships with the SDK 3.0 :-) fully encapsulates the libspe2
interface, so we would never actually 'see' the loaded kernel. All we do
is pass various names (char const *) to ALF to allow it to dlopen /
dlsym the appropriate symbols. I'm not even sure we can query these
strings from ALF. (In CML I implemented a 'user-space' analog of the
task-info for caching purposes, as the latter has become an opaque
pointer, and thus doesn't allow us to implement a comparison operation.)
