I'm not at the machine right now (don't have access to see how the video looks), but this should only change the operation of the booting of the kernel, rather than the availability of the Grub menu.  On machines which use grub1, I have the following:

"terminal --timeout=1 serial console"

currently, for grub2, I have:

"terminal serial"

no timeout value, and no option to pass both serial and console in - apparently grub2 does not support the timeout option for that line.

thanks,
