Some ideas not for speeding it up as a whole but for making it
spend its time when it's less noticeable:

If booting from SD, you could put things you don't need in the
initramfs into a regular file system partition or image that gets
mounted later. That way, you can interact a little bit earlier.
Drawback: more complex to set up than just a single file.

Likewise, you could initialize drivers you don't need immediately
(e.g., storage) by loading them as a module, so they disappear
from your critical path to first interaction.
