Subject: PPC405 RTC not working

I am currently trying to get a M41T65 sensor to work on a PPC405 based
board.  I am using the 2.6.26 kernel with a backported version of
rtc-m41t80.c (from 2.6.30).  Everything compiles and loads fine.  However,
there is no /dev/rtc node created.  "/proc/devices" returns "254 rtc" (which
I feel isn't correct).  And "/sys/bus/i2c/devices/" list nothing for the
RTC.  I do see the information from the device tree in
"/proc/device-tree/plb/opb/i2c@ef600400/rtc@68/"

Here is my dts information:
 IIC0: i2c@ef600400 {
                                compatible = "ibm,iic-405exr", "ibm,iic";
                                reg = <ef600400 14>;
                                interrupt-parent = <&UIC0>;
                                interrupts = <2 4>;
                                index = <0>;
                                rtc@68 {
                                        compatible = "m41t65";
                                        reg = <68>;
                                        };
                        };

Thanks!
