The RTC driver doesn't make much sense without interrupts... look at the API in include/linux/rtc.h. Without interrupts, you are just querying the RTC status, which (I am guessing) is different on the M58T35.
So, with no interrupts and a different status byte output, it sounds like a completely new chrdev driver to me... :)
BTW, Andrea, since I think (???) this was your patch, why do you disable RTC interrupt on Alpha platform? You might as well disable the entire driver at that point IMHO...
