Also, you were correct that removing lapic from the cmdline allowed the previous version to run at full speed. Now, how can I tell if the patch is doing its thing? What should I be seeing? :) Functionally, it looks like it's working. There were a number of compiler warnings you might wish to fix before calling it good. Such as "initialization from incompatible pointer type" several times in dyn-tick-timer.c and a "too many arguments for format" in dyn_tick_late_init.
