Inline CSS instead of linked file

Hi again!

I’ve spent a few days to manage with this task, but it seems a bit complicated.
The thing is I want to output inline css instead of <link> tag in the head, but:

1) wp_head – it’s just action with hooks with no real data, only simple output.
2) the combined and minified scripts loads the same way without wp_enqueue.

So… is there is any way to achieve the desired result?
Thanks.
