Thanks!  That brings the early timings on epia-cn to:

00.005: <00>

The romcc code is a little faster (~16ms), but that's only because I
hacked it to read the coreboot_ram file into cache while waiting for
the smbus power well to stabilize.  (With car it isn't possible to
seed the cache, but that's not a big deal.)
