That would probably be because it is using UEFI text mode rather than VGA text mode.

Oh, I didn't know UEFI text mode didn't use VGA text mode! That could be an important consideration. But I suppose you can still frob the VGA registers to set VGA text mode, right? Even if you boot under UEFI?
While that way work on some hardware, on a lot of hardware it won't.
