Interesting. So some call must be failing on the 2nd core and cgminer is disabling ADL on that card inappropriately. I think I'll just enable ADL on any AMD recognised card.
Do you get anything useful with ADL in the message if you start with -D -T ?
The only ADL message I get is a "Failed to ADL_Overdrive5_FanSpeedInfo_Get" right at startup:

I can confirm that even aticonfig throws an error when trying to get the fan speed of the second GPU:
First GPU:
aticonfig --pplib-cmd="get fanspeed 0"
Fan speed query:
Query Index: 0, Speed in percent
Result: Fan Speed: 100%
Second GPU:
aticonfig --pplib-cmd="get fanspeed 0"
PPLIB command execution has failed!
ati_pplib_cmd: execute "get" failed!
