Yes, there were more in /var/log/syslog:

Mar  2 15:16:45 darkstar kernel: radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=325.00 Mhz, System=200.00 MHz

Do the "seems to be busy." and/or "Failed to register I2C bus" 
indicate a problem ?

There's nothing about radeonfb in dmesg because I manually 
loaded the modules.

I now compiled built-in with debug enabled and got the same 
problem. Nothing got logged. Everything seems to stop when it 
blanks, but SysRq works.
