Jeremy,

I understand all of this.
In subject line and earlier messages I say that I am interested in
mountroot prompt - the prompt where kernel can ask about what device to
use for root filesystem.
Essentially I would like kernel to recognize USB keyboard (and disable
all the legacy stuff if needed) before it prompts for the root device.
