[ 2.505134] [Firmware Bug]: powernow-k8: No compatible ACPI _PSS objects found

I get this error since for ever and i heared that there might be a solution by modifing DSDT file and recompiling it.
But i never done this can someone who did paste me o foward me a link and also i wanna know if it is posibile to make a patch that can be aplied to later kernel upgrades.
My Bios version is LENOVO 01976HG/INVALID, BIOS 6ZET37WW (1.24 ) 06/15/2011.
I didnt know when i bought it that it will have a faulty bios that is never going to be fix.
Thanks in advance for ur answers.
