It seems ATA is already working on more machines (this is my personal
experience, as I have 2-3 machines that fail to boot at all with IDE,
and every machine I've tested works with ATA so far).
As far as testing:
I've been using ATA exclusively on all machines I test now... for
months. And I know I'm not alone.
But it seems we can't get it widely tested without actually switching
to it by default :P I have heard several people ask why it's not the
default in IRC. Is there *really* a good answer for them?

This is still the only instance I've heard where it doesn't work on a
machine while IDE does ;)
I believe using ATA will make a much better option for Alpha
personally - even in its current state.
