Subject: RTC problem in PS3

	Hi I've compiled the latest version of linux kernel (2.6.27.6) in my
PS3 running debian and get a warning message listed here

	Setting the system clock.
  	Cannot access the Hardware Clock via any known method.
  	Use the --debug option to see the details of our search for an access method.
  	* Unable to set System Clock to: Sun Nov 16 20:33:06 UTC 2008


	The problem can be reproduced with the commands

	# hwclock --debug
 	hwclock from util-linux-ng 2.13.1.1
  	hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
  	No usable clock interface found.
  	Cannot access the Hardware Clock via any known method.
  	# ls -l /dev/rtc*
  	ls: cannot access /dev/rtc*: No such file or directory

	Loading the rtc-ppc module solve the problem, but after restart
the system I still have the problem. Looking at kernel config I change the
rtc-ppc to be build into kernel and this solve totally the problem. So the
ps3_defconfig must set the rtc-ppc to be build into kernel.

	Thanks in advance.
	Fabiano.
