FUD.
It would be far easier to hack into those systems because they are open-source if they *were* as vulnerable. All the potential bugs are immediately visible.
M$ OTOH onscures its source code so it takes a lot of hit and miss to determine if a vulnerability exists.
More FUD.
I've been using ACPI in a 2.4 kernel for well over 2 years. The "trial" 2.6 has been working for a year.
The Windows "working" version can't handle standby-hibernate in my new laptop after a "service" pack upgrade. Linux's works; with some limitations because the display drivers that are proprietary (binary-only) do not like it.
As for computer-controlled steering; as long as Micro$oft Quality remains acceptable in software, I won't have a bar of it. Vendors have not inspired a great deal of confidence in their implementations of stability controls, etc. It doesn't *matter* that they work most of the time. The have to work ALL OF THE TIME.
