Ehm it's 256 now and it has been for a looong time. The few cases I've seen where people claimed it broke, turned out to be something else. I've still haven't seen a valid report on this.
It might sound obscure that 0 means 256 sectors, but it's really not a hidden obscure fact - people do know. I'm all for being conservative where it matters, but I'm siding with Jeff on this one. I suspect that Windows uses 256 as well, which basically means that we're in the clear.
