^^^^^^ culprit !
Send me the raw PNP resource data so I can look into this:
1) Search for the right two-digit PNP handle for device "0104d041":
cat /proc/bus/pnb/devices
01 0104d041 07:01:00 0080
02 0105d041 07:00:02 0180
03 1005d041 07:00:02 0180
04 0007d041 01:02:00 0003
...
The number in the first column (here: 01) is the handle
to be used in step 2.
2) Send cat /proc/bus/pnp/01 | od -tx1
