I am experiencing the same kind of problems that you describe. I am not
aware of any options in the XF86Config-4 file that fixes the problems.
Having said that, I have to say that I dont find the problems to hinder the
kind of work that I do.

- I dont usually need to get into a text console, once I am using X.
- It would be nice to play video/DVDs .....I expect this will be fixed
soon.

My most serious concern is not being able to have the LCD panel *AND* an
external monitor on at the same time. I need this during presentations....
