Can't get Enhanced Speedstep working

[Stefan 'Steve' Tell]

Hi,

I cannot get Enhanced Speedstep working on my new laptop (Medion MD98000).  
Maybe you guys have an idea ...

,---- [ dmesg | grep est ]
| est0: <Enhanded SpeedStep Frequency Control> on cpu0
| est: CPU supports Enhanced Speedstep, but is not recognized.
| est: cpu_vendor GenuineIntel, msr 6130a2c06000a2c
| device_attach: est0 attach returned 6

You can get a full 'pciconf -vl' here:

You can get a dmesg-output here:

 * <http://zeus.crashmail.de/nopaste/?497>

You can also get a full 'acpidump -t -d > medion_md98000_acpidump.asl'  
here:

 * <http://daemon.crashmail.de/~stell/freebsd/medion/medion_md98000_acpidump.asl>

Can I provide any other information? Any hints how to get this working?

Thanks in advance again.
