Are you using the remote that was sold with the card or some other 
remote? Looking at the dmesg you posted, I think the rc5_device number 
of your remote is 5, so could you try loading the module with 
"rc5_device=5 ir_debug=1" and alternatively with "rc5_device=255 ir_debug=1".

Should that not work, then you could also try the same two alternatives 
but with ir_debug=0 since the extra printk's can cause the driver to 
lose some events.

The word "autodetect" might be a bit misleading. It's rather that it is 
set to a default value based on which card you have (in your case that 
would mean that it is set to the rc5_device of the original remote).

If you want the card to listen to any rc5 code, use rc5_device=255 as a 
parameter (note though that it may then pick up unrelated commands from 
other remote controls if they are also rc5).

Or you can do as Jouni and load the driver with ir_debug, then press a 
few buttons, and then look in dmesg for bytes with a value in the range 
0 - 31 (0x00 - 0x1f), that should be your rc5_device number.
