One question for patch

xen-cpufreq-amd-powernow-k8.diff

What about line number

140 +    __update_vcpu_system_time(current);

This makes trouble while trying to compile (implicit decalaration of
function...). As I could read in the Changelog, this was removed
sometime ago.

changeset:   9644:8821da562fe0
user:        kaf24@xxxxxxxxxxxxxxxxxxxx
date:        Sat Apr 22 10:29:27 2006 +0100
summary:     Remove update_vcpu_system_time() call from the per-VCPU timer

Do I also need one of these patches:

cpufreq-xen-dom0-func.diff
cpufreq-xen-linux-2.6.16.diff

I tested only the first patch. To get the xen-3.0-3.0.2+hg9681 compiled,
I commented out the line shown above.

The system seems to start and powernow-k8 seems to work. But something
still seems to be wrong, because the nvidia driver crashes and it does
not crash with the same kernel in native linux mode (Not booted in xen).

I attached the nvidia dump. Maybe you could have a look at this :-)

At the moment of this writing, I only can use the nv driver and this one
only supports 1024x768, so this is not really funny on an 19" LCD ;-)

But so far, thanks very much. I hope you still may/want to help me with
this issue.

Christian
