Did you have to do any debouncing-type of trick for this? I tried switching to the CHANGE trigger, and wondered if it failed because the level hadn't yet fully risen to "high" when the int fired.

I think the space savings was only about 80 bytes, by combining the interrupts, but potentially the free pin could be more valuable.
