I see. Should sun4m use these functions too? On the other hand, there
is no need to be too independent on Sparc, because I think all Sun4u
machines use m48t59 and sun4m machines have either m48t08 or older
m48t02 (not supported yet). So if you prefer, sun4u could use the same
approach as sun4m and not use these functions?

Works fine here, thanks.
