Finally my wireless card and sound card are working well (Acer 7520-5626)!!!!!!!!!!.
I want to thank all of those people that develop, integrate, and support Sabayon distro, thanks!.
It is really a nice distro, but in my case after a while, i was not able to do my wireless atheros ar5007eg and hda sound card work.
My solution was to install Mandriva 2008 (it detected my sound card and my wireless card out of the box -using ndiswrapper), and also i think the package installation/uninstallation is easier on Mandriva.
Thanks, i really appreciate the help you gave me.
