I have my taylor-made kernel compiled with all and only the drivers I need, without an initram and with EFISTUB, directly called by the UEFI as its first boot option. That's how I manage to boot in 5 seconds. Then I have some distro-supplied kernels, with initram, modules, non-standard parameters AND grub, just for those times when I need something exotic. I have to stop the normal boot with Esc and select the second boot option from the UEFI menu, that points to grub. It's clumsy and slow but I just need it once in a blue moon.
