Why no Linux?

Citation for transition state costs
"The deeper the C-state, the longer it takes to leave it, and the more energy this transition costs." - http://software.intel.com/sites/default/files/absolute_power.pdf . Also "Fequent [sic] transition in and out of deep C-States can result in a net energy loss." - http://impact.asu.edu/cse591sp11/Nahelempm.pdf .

Windows 8 kernel is tickless
This Ars Technica article about Windows 8 states that Windows 8 kernel is tickless - but there seem to be nearly no official references to a major change being made between Windows 7 and Windows 8 in offiical Microsoft documentation (the best I found was http://blogs.msdn.com/b/b8/archive/2011/11/08/building-a-power-smart-general-purpose-windows.aspx ) - others have commented on the lack of docs too (http://arstechnica.com/civis/viewtopic.php?f=20&t=1185787 , https://code.google.com/p/chromium/issues/detail?id=153139#c71 ). Some have also noticed the change observationally - http://www.thesycon.de/deu/latency_check.shtml .
