It does. I have the same problem on my ThinkPad R40 after upgrading to
the latest X.org in etch.
The image is sent both to the LCD and the external screen in text
mode, like I want, but when I start X, it switches off the LCD if an
external monitor is connected, and it won't send to the external
monitor unless it's connected when I start X.
So, to switch between them I have to restart X. This is pretty
annoying, so I'm hoping someone has an explanation as to what has
changed here.
For the record, turning on the external display with radeontool
doesn't work either.
