It seems the pattern we use for parsing Intel driver
\(II\) (.*)\(\d+\): EDID for output (.*)
is gone on some systems with 3.11 kernel (e.g. 201302-12843).

However, it still can be found on the very same system with 3.8 kernel, as attached here.

For an older chip (third generation Intel graphic controller) on 201202-10402 with kernel 3.11
We can still find that pattern, despite the fact that the driver version is also 2.99.904

I'm not sure why there is such a difference.
Looks like it's not a kernel/driver related, the possible answer might be the difference in the graphic controller model.

This concludes that the script needs a new pattern for system without the EDID pattern.
