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. -- Andriy Gapon
