Rudolf,

I'm not really familiar with this, so I'll trust it to you if you don't
mind. :-)

If it helps any, the output from LSHW for the CPU section is below:

Yes,

This is not yet in our detection table. Here is what we know:

TYPE  FAMILY  MODEL  STEPPING
0       6       7       0+   something special EDEN ESP samuel 2
0       6       7       8+   VRM85 C3 EZRA
0       6       8       0-7  VRM85 C3 EZRA T
0       6       9       0+   VRM85 NEMIAH
0       6       9       8+  max1718 C3-M

max1718 => Notebook CPU Step-Down Controller for Intel
 Mobile Voltage Positioning (IMVP-II)

http://www.egevo.se/dokument/max1718.pdf
http://www.maxim-ic.com/products/power_supplies/imvp.cfm

VID "something special"
1 1 1 1  1.30V
1 1 1 0  1.35V
0 0 0 0  2.05V


We need to define 2 new VIDs one is something called

IMVP-II (I dont know anything about -I and -III  => will call it 1718

and the that really strange samuel 2 VID codding. => will call it 670

Ideas? Questions?
If not I will develop the patch.

Regards
Rudolf
