Great.

So we do something without break backward-compat with older a800-devices.

Implement the 

identify_state

function pointer and in there you look if the revision is the new one 
(yours) then cold = 0 otherwise cold = 1 - which forces a firmware 
download.

The no_reconnect-field should remain 0. 

Can you do this and send the patch along with signed-off-by? I will 
commit when Martin reports success.

regards,
Patrick.
