Vladimir Serbinenko (phcoder(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3408 -gerrit commit a2e7d6aef8aa5a5ec96ac18644441f487d88f7dc Author: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Thu Nov 14 19:22:27 2013 +0100 Make version look like something thinkpad_acpi would accept thinkpad_acpi checks that BIOS version matches some pattern. Report version in this form. Not cleaned up as the idea of this patch seems to be met with resistance. Can make it Thinkpad-specific if the idea is accepted.
