So, I've got a 7350 here with the RTC option (big ass IC).  The stock kernel 
works fine with it but a 3.0.4 kernel I built myself was having trouble.  I 
could set the RTC with hwclock just fine but it would "forget" on reboot.

Examining dmesg output showed me the following:
ep93xx-rtc ep93xx-rtc: rtc core: registered ep93xx-rtc as rtc0

This makes no sense at all given that the ep93xx driver is configured as a 
module and the m48t86 is configured as built-in in the kernel.

But, if I recompile the kernel with the ep93xx to be built-in, I get a second 
rtc entry in /dev (rtc1).  And if I run hwclock --rtc=/dev/rtc1, it works just 
fine.

So, why would ep93xx be used if it's not even loaded?
