These are functions of a shell (like bash), which you haven't got yet during
kernel boot. You can read the kernel boot messages _after_ your system's up
using dmesg etc.
If you can't do that, e.g. because your kernel always hangs during boot, you
could enable a serial console in your kernel and watch/log your kernel 
messages with a terminal program running on a different computer.
