top(1) CPU states display is messed up

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

I recently upgraded amd64 NetBSD-5.1 to NetBSD-5.1_STABLE, and I noticed that 
top(1) CPU states lines are messed up, i.e. this is what it looks like:

load averages:  0.20,  0.17,  0.09;               up 0+00:05:29        11:51:44
45 processes: 43 sleeping, 2 on CPU
CPU0 states:  1.0% user, 0.0 % nice 0.0  % syste 0.0   % interru99.0    % idle
CPU1 states:  1.0% user, 0.0 % nice 0.0  % syste 0.0   % interru99.0    % idle
CPU2 states:  0.0% user, 0.0 % nice 0.0  % syste 0.0   % interru 100    % idle
CPU3 states:  0.0% user, 0.0 % nice 0.0  % syste 0.0   % interru 100    % idle
Memory: 121M Act, 39M Inact, 1460K Wired, 31M Exec, 19M File, 1756M Free
Swap: 2000M Total, 2000M Free

Any ideas?
