I'm using an Iintel GMA 945 (Macbook 2.1), the above kernel does not
behave different than 2.6.33-0.46. That means:
- GDM works (again)
- No flickering at boot
- Logging in to GNOME blanks the screen, even a VT switch does not bring
the backlight(?) back. (might this just be an gnome-power problem?
related to ...)
- ... adjusting brightness does not work.
All in all the intel driver was quite unstable since 2.6.31-5.
