Hey Ben, I see no reason why you'd get flamed for such a reasonable and understandable request; many have mentioned this too.
I've no idea what will happen, but if it's any consolation, the way I look at it is that you shouldn't fire a tube amp up and grind straight away anyway - you either start very softly and work your way up or let it sit and warm up. Either way, it takes a whole lot longer than the KPA's boot time.
You've probably thought of this already, but hey, I'm just puttin' it out there, bro'.
Another thing: None of us, AFAIK, is savvy as to the size and complexity of the OS. Perhaps the KAOS files we use for updating give a clue (small), but my guess is that the core functionality might be already housed in the KPA's "firmest" of firmware. Out of my league here, but again, just puttin' this out there.
