Well, the ATA driver has just grown more standard compliant :)
You *must* hang around for 31secs to wait for slow devices to come ready,
according to the ATA specs. Now I've gone to great length before to
get around this by using clever heuristics, and I'm getting there again,
but there are *so* many crappy devices out there that it takes time
to accomodate them all. 

So if you experience long boot delays or misprobes, please boot verbose
and mail me the output from dmesg with a subject of "ATA probe fails"
and a short description of what is wrong, and I'll try to work in a
solution for the problem.

(And no I wont ever go the white/black-list route as others have gone).
