ok.... So now when my cross linuxfromscratch on an ibook G4 with kernel 2.6.30 boots, the hardware clock fails to set! The boot message is:

Setting system clock...
RTC_RD_TIME: Invalid argument
ioctl() to /dev/rtc to read the time failed.

So i tried selecting every RTC driver available in the kernel and that didnt work. Under Device Drivers-->Real Time Clock i have selected:

Set system time from RTC on startup and resume = y
RTC used to set the system time = rtc0
/sys/class/rtc/rtcN = y
/proc/driver/rtc = y
/dev/rtcN = y
And then ALL of the drivers below selected.

I tried setting the clock through hwclock and i got the same error.
Does anyone have any idea what's going on?

YAY! I got it to work! I needed to enable the protocol under Device Drivers-->Macintosh Drivers or something like that! Thanks!
