Ok, I've run radeonreg, here is the output:

Before HDMI connected:
0x601c  0x00000000 (0)
0x6028  0x06000012 (100663314)
0x6034  0x00000012 (18)
0x6040  0x00000000 (0)
0x604c  0x00000000 (0)
0x6058  0x00000000 (0)

HDMI connected:
0x601c  0x00000000 (0)
0x6028  0x06000012 (100663314)
0x6034  0x00000012 (18)
0x6040  0x00000000 (0)
0x604c  0x00000000 (0)
0x6058  0xff000012 (-16777198)

HDMI disconnected:
0x601c  0x00000000 (0)
0x6028  0x06000012 (100663314)
0x6034  0x00000012 (18)
0x6040  0x00000000 (0)
0x604c  0x00000000 (0)
0x6058  0xff0ff000 (-15732736)

The value of reg 0x6058 changes (HDMI-0). As you can see, after HDMI has been
disconnected, it is different from the original value (0). I suspect that there
is some problem with this?
