install the HW Sensors to S/L/E IntelCpuMonitor doesn´t work from Extra. I deleted in SuperIOFamily already all plugins that aren´t needed to make boot time shorter
to get proper speedstepping you have to check first Generate P-States, Generate C-States and Drop SSDT in Chameleon preferences.
but it won´t start throttling before setting the needed model id in smbios.plist
according to the hardware specs of the Acer6292 it should be MacBook3,1 , because the closest match is the MacBook late 2007 - but this won´t work!
MacPro3,1 would give you speedstepping, but avoid some functions. to keep everything working (i.e. coolbook if needed)
I decided to follow silencers guide here

and to create a legacy.kext for the acer6292. all credits to him !
put the attached legacyAcer6292.kext in Extra and set the model to MacBook3,2 in SMBios.plist, reboot -
et voilá! speedstep is working! you can proof it with voodoomonitor

p-states in vodoomonitor - throttling at lowest p-state - highest p-state
you can see the throttling also in the free version of coolbook and use it to raise the cpu load for testing

all needed files are in the attached package, except iStat for measuring - look for last free version 2.0 or you have to buy it for 16 bucks !
EDIT: if you experience kernel panics, get rid of iStat or other hardware sensors !
