Yes, it works here with CLOCAL(Ultra2, type-5 keyboard).
With OFWCONS_POLL_HZ=20 and TERM=sun I get almost working console.

However, ofw console is still too slow to work on.(IMO) I tried
syscons + creator to get more speed by hardware acceleration.
To build that kernel, I had to add <sys/modules.h> to source files.
(I guess it was both sys/dev/fb/creator.c and
sys/sparc64/creator/creator_upa.c) After really fast booting
message scrolls and login prompt, the machine locked up. :(
