I tried it on amd64; I'm not sure what to look for.

Did you mean to leave that commented? Anyway, I ran the program with and 
without the line commented.

bugfood at bugfood:/tmp$ gcc rtc.c
bugfood at bugfood:/tmp$ ./a.out
value: 0
bugfood at bugfood:/tmp$ echo $?
9
bugfood at bugfood:/tmp$ sed -i s://::g rtc.c
bugfood at bugfood:/tmp$ gcc rtc.c
bugfood at bugfood:/tmp$ ./a.out
value: 0
bugfood at bugfood:/tmp$ echo $?
255


So, I guess the ioctl fails, but I don't know if that's what you're 
looking for. MPlayer runs fine with rtc timing on my machine.
