Core 2 Duo for laptop CQ40-314TU

I have found something about CPU Upgrade on the Intel's Website, the manufacturer of my laptop's chipset (GM45 Chipset). Currently, the CPU which this laptop is using (Dual Core T3400) is NOT in this list: http://ark.intel.com/chipset.aspx?familyID=35509
The laptop's chipset also support Core 2 Extreme Technology, which I think the latest CPU Technology.
I have another laptop called Acer Aspire 5572ANWXMi that is using the chipset 945GM which support the T7600 (like you suggested) and it is in this list: http://ark.intel.com/chipset.aspx?familyID=22816
