Yes.
How short does it have to be, and can't we have a kernel bootparm to
override the cable detection?
For most users the goal should be to automate behaviour. It should just
work.
What's the max length of a 40wire cable to sustain 80wire cable
characteristics?
This is normally only the case on a laptop, where the cable is
essentially just a tiny stub between the motherboard and the drive. I
suspect this is something that the system manufacturer has to validate
works properly, more than any hard and fast limit.
For a normal desktop PC, it would be far better to just use an 80-wire
cable.
