GoogleEarth and fglrx have been known in the past to have not played 
well with each other, and GE is a pain to use without the 3D support if 
you use the radeon driver.  I have no experience with the radeonhd 
driver yet (it also does not play well if you even have fglrx 
installed!).  In the past the combination of GE and fglrx has been known 
to freeze X on the second invocation of GE.  a Hard freeze, requiring a 
reboot since all keyboard is lost.  YMMV  More recently, its been better 
but still not without problems.

It might confuse syslog which keeps the file open and stores file 
positions for where to write the next message.  You may have mixed 
results doing this.  It probably best done just before logrotate 
runs....but I won't swear to this.
