Review Comment:
   Sure, it would be more generic of course. Although, instead of making 
another list, I'd rather just search the drivers by device node name from 
filesystem in that case.
   
   I actually have a draft ready, I'll clean it up, test and push it tomorrow 
for review, perhaps it is better :)
