Your suggestion on the brightness actually helped me. Thank you very much.
I was also able to set up alsa and it is working great. I set up xbindkeys for the brightness keys and for volume control. If you're not aware of it, please read:

')I will try to get the hdmi output and the brightness buttons to work when I have more free time (xbacklight returns "No outputs have backlight property"). Was anyone able to properly set up the video drive? I am using fbdev. Any alternatives?
I've been changing brightness
via ACPI.
I added
$this->bbcode_second_pass_code('', 'chmod a+w /sys/class/backlight/pwm-backlight.0/brightness')
to /etc/rc.local to add write permissions to the backlight file and use a couple of hotkeyed scripts to increase/decrease brightness. E.g. scripts like the ones
here work fine with the paths changed, BRIGHT_INCREMENT set to an appropriate value, and MIN_BRIGHT to 0 (if you'd like to be able to turn off the backlight).
XFCE's "Brightness Panel Plugin" also works if you're using XFCE.
edit: Just realized you were asking about video drivers, not brightness -_- Anyway, the alternative is the armsoc driver, which Chrome OS uses, but it's slower than the fbdev driver since 2d acceleration doesn't work properly. Take a look at Siarhei Siamashka's comments in
this video and in
this post for more info.
