Do you happen to be running Xen?

I just did a quick google for "4gb seg fixup" and found zillions of entries, all
related to Xen as it seems - the quintessence of the articles being that the
severity of the messages probably ranges from cosmetic to a performance issue
(depending on how frequent they appear), that it affects various different
programs running under Xen, and that you need to replace a certain library with
a "Xen-friendly" version to get rid of this (details are mentioned in most all
the googled articles).
