But if you use xtreg, fe the vce() option doesn�t allow
cluster so that still doesn�t answer why cluster after
xtreg, fe was allowed in Stata 9 but not in Stata 10.

You can use xtivreg2 (ssc desc xtivreg2) to apply the cluster option to an xtreg, fe model in version 9.2 or 10. You need not have any instrumental variables.
