The main issue with your proposed implementation is that it is recursive and will use more space in stack frames than the existing implementation uses in creating a fixed-size buffer.

It is also worth noting that the existing print_int_ function in the bootloader is derived from one found in the libc and has a complex history; much of its seemingly odd design stems from support for padding and alignment options which have been removed in the bootloader version.

Recursive in assembler makes one div per character, and div is a very slow operation

This whole discussion is moot as this function is never used. The one place where the bootloader prints arbitrary decimal integers is the video mode selection screen, which uses a different implementation.

I'm just sharing my experience, the choice is yours (:
