If by chance you have a Sun Ultra 40 M2, it's now supported by upstream Coreboot for freeing your BIOS.

The Sun Ultra 40 M2 is a dual Socket F workstation with NVIDIA MCP55 chipset. This board supports two, dual-core Opteron CPUs with DDR2-667MHz memory. This Coreboot port is working, but having memory on the second node causes the RAM initialization (raminit) to fail.

The Sun Ultra 40 M2 port can be found in Git. For other hardware recently supported by Coreboot/Libreboot, see our other recent Coreboot news.
