Ohh well, that is my fault.
I accidently removed the centrino driver for x86_64.
Instead of only removing an old flag:
# CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI is not set

this one also was unset accidently:
CONFIG_X86_SPEEDSTEP_CENTRINO=m

Can you try this one:
ftp.suse.com/pub/people/trenn/10.3_cpufreq_centrino_x86_64
I hope there are no dependencies and the config got reset again, please double
check with:
zcat /proc/config.gz |less
and search for CONFIG_X86_SPEEDSTEP_CENTRINO, it should be set to =m.
As a matter of fact is it! But anyway I still there is no cpufreq support, at
least from what I see in kpowersave and what I saw during bootup :(


Do these ACPI error messages go away with the new kernel?


ACPI Error (dsopcode-0250): No pointer back to NS node in buffer obj

ACPI Error (psparse-0537): Method parse/execution failed [\_PR_.CPU0._PDC]

ACPI: Processor [CPU0] (supports 8 throttling states)
