jumpin jesus,
unless you happen to have your terms slightly confused then the short answer, in line with asaris is no.
if, however, by omniscience you are actually thinking about something like predestination then its clearly another story.
for an interesting take on the whole notion of free will and what it means for people I reccomend the work of a russian existentialist thinker nikolai berdyaev, particularly his book 'the destiny of man'. as a teaser he suggest, contends, holds, that man and his free will is necessary because creation is incomplete and in order for us to work with god to complete it a truly free will is necessary. one of the reasons to advance this notion is to do away with the concept that free will is really only a 'choice' between good and evil where everything is set up and all we need to do is choose our alegience (sp?).
