[geeks] OS's that support Hyperthreading on Xeon DP

[Chris Byrne]

Well Dell systems have been using it since it came out. It's the only OS
supported by Dell on their XEON server boxes. I seriously doubt it makes
much performance difference though. Every HT benchmark I've seen has
shown very little if any improvement excpeting some VERY tailored ones.
In fact some of them show a decrease (overhead?)
