About 150K compiled on x86 (before linking so that has symbol information
etc in it).

It is small, but for the purposes we need it for it wasn't possible to
put the code into user space. We thought about keeping it in user space
but unfortunately the code is needed when the framebuffer console driver
initialises which is very early in the boot sequence. So unless there is
a way to spawn a user mode process that early in the boot sequence (it
would have to come from the initrd image I expect) then the only option
is to compile it into the kernel.
