The bug has been fixed; revisoion 5928023cef87847a295035487397b9ec701fdd6b is still broken, but dbd99ae302be8f51b547fb6283c91d0c9859b7d5 works. I haven't determined which of the commits inbetween fixed it, but the BIOS update of 15faf946f7a17a5fab0d05a2312d43249d81af3 seems like a likely candidate.
