Maybe there was misunderstanding on my previous comment.
What I wanted to let you know is that the parser in igt doesn't know 
(yet) how to deal with "engine=%u:%u".
The ordering of the field doesn't matter though.

Updating the parser is probably a one liner. There is some interesting 
logic behind though that expect the engine ids to be contiguous numbers.
