Upgrading a ROM based KEXT

Hi All,

I have my kext which is burned in the ROM of my PCI card as a property. Now i want to upgrade my driver without flashing the ROM. I created a driver(kext) for my card with a higher "CFBundleVersion" property.
I placed this new KEXT in the "/System/Library/Extensions/" folder and touched the folder; executed shell command "touch /System/Library/Extensions/". The first time the OS rebooted my new KEXT got loaded, but thereafter for further reboots the KEXT in the PCI ROM gets loaded.

Now when the new KEXT is present in the "/System/Library/Extensions/" folder, Why does the old KEXT from the PCI ROM is getting loaded?
