You're right, there was no idle driver, but the idle process from process_64.c which called the idle routine. I reported my thoughts on this on 14th of May this year 2010, mostly claiming for a standard on where to report these events. You're also missing the other idle routines from x86/kernel/process.c mwait_idle_with_hints and mwait_idle only throw start events, so they should behave like default_idle. poll_idle on the other hand reports the end event itself.
