[Hardy-Gutsy]problems with Sound, atheros, webcam, compiz in my Aspire 5720z laptop

Hi!

First, sorry, my english isnt amazing :(

Now, i bought a Acer Aspire 5720z laptop in december, but when i installed ubuntu 7.10, had many problems.

The sound not work (alsa-mixer and the sound of the system are ok configured), compiz fusion effects couldnt be enabled, and not recognise my Crystal Eye integrated camera, and the Atheros Wifi card.

In Hardy alpha 1/2 the problems persists, but ...... in alpha 3, the compiz effects could be enabled and works fine ^^

The compiz effects are solved .... but the sound, ath, and crystal eye.... no :(

Madwifi drivers are including in ubuntu, but .... why dont recognise my wifi card¿?

My Wifi card is AR5007EG, and my graphics Mobile Intel(R) 965 Express Chipset Family.

In "hardware information" ubuntu recognise all of my hardware, but i cant connect to any wifi network etc.....

Thanks, Bye
