There is a kernel config parameter called CONFIG_HPET_EMULATE_RTC, that if defined in the kernel config, will cause the behavior that you're seeing. I have not looked to see at which version that option came in. However, I think support for RTC in dahdi_dummy is best dropped. There is a patch on mantis (http://bugs.digium.com/view.php?id=13930) against dahdi_dummy that allows it to provide accurate timing with standard kernel timers that you may want to try.
