I fixed top, ps, and more. http://www.cs.uml.edu/~acahalan/linux/procps-990103.tar.gz
You can set HZ to 1024 without recompiling. You don't have to make /proc report values as if HZ had not been changed, but you could. It is your option.
That also includes:
CPU time info is correct for the very first time. Unix98 pty devices are shown. Both "ps aux" and "ps -ef" work now, and you can mix them freely. You don't have to update /etc/psdatabase when you recompile Linux. You don't have to update /etc/psdevtab when you change /dev. Processes can be selected by name. ("ps -C xterm,nxterm,rxvt") Formats are totally user-defined. ("ps -o ruser,euser,pid,cmd")
Isn't it time you upgraded?
