where is that documented?  tbh, i've never noticed those options at
all.  checking here,

  
http://wiki.xensource.com/xenwiki/?action=fullsearch&context=180&value=clocksource&fullsearch=Text

those references only mention clocksource= @kernel line, and the xen
user's manual doesn't mention the term clocksource at all :-/

there's no mention

checking those now ... will report results in a bot.

thanks.
