Here is an Apple list of Intel Mac models with relevant EFI and SMC firmware updates. The article shows you where to identify the status of your machine with respect to these updates. This may resolve your EFI and boot selection issue.
And here, is a Mac OS X Hints article on how to create an AppleScript to select the boot volume without traveling to System Preferences, or needing to wait on the option-key boot selection. Thought you might appreciate this in case the EFI thing doesn't work out.

I tried to install the EFI firmware updates but it tells me my computer doesn't support this software.
The AppleScript didn't work for me either. Just kept rebooting into OSX.
