For your graphics card, install this firmware package:

   x11-drivers/radeon-ucode

Then, enable the following options in your kernel configuration (the 
usual "make menuconfig" deal):

   Device Drivers -> Graphics support ->
       <*> Direct Rendering Manager ->
           <*> ATI Radeon
           [*] Enable modesetting on radeon by default

In the "Support for frame buffer devices" section, make sure that all 
other drivers (including the VESA one) are disabled, or else its going 
to conflict with the Radeon modesetting driver.

In your /etc/make.conf, use this:

   VIDEO_CARDS="radeon r600"

Now for your sound card.  According to your mainboard's specs:

   http://www.asus.com/Motherboards/AMD_AM2/M2AMX/#specifications

It has an ALC662 audio chip.  That chip is made by Realtek.  So in your 
kernel config, enable:

   Device Drivers -> <*> Sound card support ->
   <*> Advanced Linux Sound Architecture ->
       [*] PCI sound devices -> <*> Intel HD Audio ->
           [*] Build Realtek HD-audio codec support

Now build your new kernel (make) and install it (make modules_install && 
make install).  Make sure Grub is set up to boot from it next time 
(don't reboot yet.)

Since above you changed your VIDEO_CARDS variable in make.conf, you can 
now do:

   emerge -auDN --with-bdeps=y world

and it will automatically install the correct X.Org driver (which should 
be "x11-drivers/xf86-video-ati" and will be installed automatically as a 
dependency).

After you've done the above, make sure that you do *not* have an 
/etc/X11/xorg.conf file.  If you have one, delete it (feel free to back 
it up first.)  Also make sure you don't have files in the 
/etc/X11/xorg.conf.d/ directory that try to configure your graphics card.

Now reboot and you should have working 3D acceleration with KMS and DRI2 
and sound.

If everything works OK, you can now do:

   emerge -a --depclean

in order to uninstall any old, unneeded drivers and deps.
