Andres, everyone!

We do not encourage people to build their own LinuxBIOS, unless they are
involved in LinuxBIOS development.

Given that we have a problem with which toolchains can correctly build
the BIOS image, and the failure results so bad (unless the person has a
PLCC flash part), only *tested* bios images we "bless" should be
installed.

>From last night's status call, I believe the next build (87) should have
versions of LinuxBIOS which should set the PS/2 port properly.

Yoshiki, please wait until the next build is available.
                                    Regards,
                                            - Jim
