Linux Assembly How To: “Hello, World”

I find these assembly demos that rely largely upon system calls lacking. I know much stuff cannot be done without system calls, but there's got to be a better "Hello, World" for assembly.

What would a "better" "Hello, World" for assembly look like?

Not necessarily "better", but lower level and without the use of syscalls: on bare-metal x86 protected mode, writing characters to "video memory" (from 0xB8000, normally).

IMO, bootloader/video memory is quite a distance from the traditional model of what "Hello World" is meant to be about, no? If anyone's interested, there are lots of very simple bootloader Hello World goods around:

I don't know, and that's part of the reason why I raised the issue.
