Well.. if it isn't harmful in any way, and if we would do it on x86_64, then we should also do it on i686. Having as consistent a baseline as possible is good.
Agreed.
As to actually doing it, are there any ramifications due to the potential for tracking additional cpus (timeslice allocation algorithmic changes?) that would be a noticeable performance inpact for people running 2 or 4 cpus?
"This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 255 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image." That's all they say about it.
