Temporarily prevent login items while using FileVault2

Hi everyone,

in the past you could hold down shift while logging in and this would temporarily disable your login items so no windows would pop up. This still works in 10.9, but only when I am on the regular login screen. I am using FileVault so I have to enter my user password before the boot process and this user will get logged in. How can I achieve the shift key behaviour with FV enabled?

Thanks

Björn
