Can you send the full debug log of the failed boot?

A failed write to 0x43 sounds very odd - it could be an incomplete
hardware configuration in coreboot, or it could be the legacy timer is
not fully supported on that board (though that seems unlikely).  You
could comment out the call to timer_setup() in post.c and see if the
boot progresses further.
