Is the fibered Ktheoretic farrelljones conjecture true for cat(0)groups?

Yes. More precisely, both the Ltheory and Ktheory FarrellJones conjectures with coefficients in any additive category have recently been proved for CAT(0) groups:
In Arthur Bartels, Holger Reich, “Coefficients for the FarrellJones Conjecture”, Advances in Mathematics 209:1 (2007), 337–362, it is proved that “with coefficients is stronger than fibered,” see Corollary 4.3 and Remark 4.4 on page 346. [Edited to clarify the relation between the “with coefficients” and “fibered” versions of the FarrellJones conjectures.]
