Indeed yes, I came across this one, with the same, if I recall correctly,
error mesages. What cured the problem for me was to specify time interval
as float, not integer. We have several Suns here with screenblanks, some
running 4.0, some 4.0.3, and a few 4.1. It seems that at least under 4.0
you could say "screenblank -d NNN" (for instance), but under 4.1 you have
to say "screenblank -d NNN.000". Weird. (Our screenblanks are also in
/etc/rc.local.) We certainly didn't have any more screenblank-related
panic since that small change.
