I suppose this has to be 

echo -ne "\e]R"

Is this some special terminal, or the Linux framebuffer works 
differently on these systems?  If the first, then either some check is 
required in /etc/init.d/kbd to avoid this echo, or a redirection is 
required (echo -ne "\e]R" >/dev/somewhere).  If the second, then perhaps 
this is a bug in the kernel?
