This didn't seem to make any difference.  I should add that it doesn't
always trigger the kernel message, but in any case it never starts
successfully (so presumably segfaults without kernel message).

When tracing the program in gdb, I noticed that the cpufreqd_log()
function was opening syslog above (ie. log_opened == 0, so it calls
openlog() to do so).  I'm beginning to think it's suspicious that adding
-V4 to the arguments makes a difference.  In fact weirdly enough, adding
-V 4,5 or 2 helps, but -V3 doesn't.  I presume adding that alters what
gets output and thus exactly when syslog is opened.

Since it's crashing on the vfprintf() perhaps it's also possible this is
a bug in libc?
