I tried something else.
I removed the write and only added a printk with a register read
to print the contents (DDC REG IS 0x...) . This is the result:
[ 0.431304] PCI: Enabling device 0000:00:10.0 (0006 -> 0007)
[ 0.626866] radeonfb (0000:00:10.0): Invalid ROM signature 303 should be 0xaa55

...
Note that the function is called twice. Is that correct?
