Well thats the living in linux... :-)
I think this notebook is perfect since, all these bugs were fixed.
Now it is almost perfect.

On the other hand think about my main notebook, acer 5720.
There suspend to ram doesn't work, and no this isn't due to GFX driver,
or anything like that. It just that BIOS doesn't pass control to linux
on resume. It doesn't like something in hardware....
This would I call a NOTHING...



I recommend to to install (if you didn't do that yet) the
compat-wireless package, or even better compile wireless-testing.

You could also patch in latest patches that fix TX power for ath5k, or
wait few days till they are in wireless-testings (maybe they are there
already...)
