I can confirm that it works fine on 8260, for example on the TQM8260: PPCBoot 1.1.6 (Apr 28 2002 - 20:22:57) MPC8260 Reset Status: External Soft, External Hard MPC8260 Clock Configuration - Bus-to-Core Mult 3.5x, VCO Div 2, 60x Bus Freq 30-85 , Core Freq 100-300 - dfbrg 0, corecnf 0x1e, busdf 4, cpmdf 1, plldf 1, pllmf 4 - vco_out 416665000, scc_clk 104166250, brg_clk 104166250 - cpu_clk 291665500, cpm_clk 208332500, bus_clk 83333000 CPU: MPC8260 (Rev 14, Mask A.0(A) 2K25A) at 291.665 MHz Board: TQM8260DBA0C7A-PJDA.201A 10399642 6 Haven't seen a 8250 yet, though.
