Well... I finally got around to testing this on sparc32, and it breaks
the new esp driver. Basically, the driver doesn't scan the bus anymore.
Obviously, this is a pretty ugly regression (after we finally got it

Attached are the bootup logs from the serial console on the SS4, one
kernel has the serial patch, the other does not, they are otherwise
identical.
