EFI will primarily impact driver initialization. If you saw a problem, it would be during the kernel startup, before the init process began, or during suspend and resume. It shouldn't impact power use or stability in general.

• Could it change (improve?) stability, power consumption, etc. if I

would reinstall CentOS 6 using the traditional boot? (or is it just a legacy wrapper around an EFI "BIOS"?)

The EFI firmware provides a legacy BIOS wrapper.
