There should be enough parts of Russ Anderson's changes in the tree to give
this a try.  It should also show up in the next -mm patch (it
missed 2.6.10-mm2).

You'd need to add some serialization in ia64_init_handler() and/or
init_handler_platform() to make sure that all the cpus didn't stomp
all over each other printing their registers, and you'll only want
one of them to walk the tasklist providing backtraces.
