It looks like some of the hardware is similar, but not all of it. The clock is not immediately obvious under ebus.
at least there is something: dma at ebus0 addr 0-ffff not configured from my Blade: ebus0 at pci0 dev 12 function 0 ebus0: Sun Microsystems PCIO Ebus2 (US III), revision 0x01 flashprom at ebus0 addr 0-fffff not configured clock0 at ebus0 addr 0-1fff: mk48t59 maybe it is a different Timekeeper installed Best Regards
