I hope that Mikael knows of some native Linux tools for this.
However, Intel did announce Vtune for Linux recently (might still be
in beta test), and there was a SuSE patch for it posted at
kernelnewbies.org also.  See:

http://kernelnewbies.org/kernels/SuSE81/SOURCES/patches.i386/50_vtune-ia32
  (warning: this is for 2.4.19)

or google for "+vtune +linux".
