The "Enhanced RTC" driver is important because it's basically a configurable interrupt generator which is designed to be easily manipulated from user-land. Many latency testing tools rely on it to measure "missed" ISRs due to overlong periods where interrupts are disabled. I suggest you compile it into your kernel STATICALLY, actually. You will find it in the character devices section. You will probably find the annoying dependency problems to disappear. =MB= -- A focus on Quality.
