Ok, it survived a buildworld on the DS20 (with EV6's) ok.
I updated it and also patched the 8- and 16-bit versions in
atomic.s as well.  The patch is at ~jhb/public_html/patches/alpha.patch
on freefall.  Feel free to commit it since you did the brunt of
the work.  FWIW, it didn't seem to make a noticable difference in
world time.
