busybox

Most Busybox questions are related to the fact that users are dropped to a Busybox shell due to some unknown issues at boot time. This must make Busybox one of the most hated pieces of software.

My problem is the opposite. I want to deliberately start Busybox at boot time either from GRUB, or even before GRUB. Is this possible? How can I do it? The purpose is to execute some commands before the boot sequence is reinitiated. So basically I want to execute some commands to make some hardware available to the bootloader.
