I've attempted to get it working, following some of the Gentoo guides.

Though, I am getting nowhere. And I don't know why.

Here's my xorg.conf (for attempted dual head):
Code:
Section "ServerLayout"

# The Identifier line must be present
# Each Screen line specifies a Screen section name, and optionally
# the relative position of other screens.  The four names after
# primary screen name are the screens to the top, bottom, left and right
# of the primary screen.  In this example, screen 2 is located to the
# right of screen 1.
# Each InputDevice line specifies an InputDevice section name and
# optionally some options to specify the way the device is to be
# used.  Those options include "CorePointer", "CoreKeyboard" and
# "SendCoreEvents".
	Identifier     "Simple Layout"
	Screen      0  "aticonfig Screen 0" 0 0
	InputDevice    "Mouse1" "CorePointer"
	InputDevice    "TouchPad" "AlwaysCore"
	InputDevice    "Keyboard1" "CoreKeyboard"
EndSection

Section "Files"

# The location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (which are concatenated together),
# as well as specifying multiple comma-separated entries in one FontPath
# command (or a combination of both methods)
# 
# 
#    FontPath   "/usr/share/fonts/CID/"
#    FontPath   "/usr/share/fonts/Speedo/"
#    FontPath   "/usr/share/fonts/TrueType/"
#    FontPath   "/usr/share/fonts/freefont/"
# The module search path.  The default path is shown here.
	FontPath     "/usr/share/fonts/misc/"
	FontPath     "/usr/share/fonts/TTF/"
	FontPath     "/usr/share/fonts/Type1/"
	FontPath     "/usr/share/fonts/75dpi/"
	FontPath     "/usr/share/fonts/100dpi/"
	FontPath     "/usr/share/fonts/local/"
EndSection

# This loads the DBE extension module.
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
# This loads the font modules
# This loads the GLX module
#    Load       "glx"
# This loads the DRI module
#    Load       "dri"

Section "InputDevice"

# For most OSs the protocol can be omitted (it defaults to "Standard").
# When using XQUEUE (only for SVR3 and SVR4, but not Solaris),
# uncomment the following line.
#    Option     "Protocol"      "Xqueue"
#    Option	"Xleds"      "1 2 3"
#    Option "LeftAlt"     "Meta"
#    Option "RightAlt"    "ModeShift"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#    Option "XkbModel"    "pc105"
# If you have a US Microsoft Natural keyboard, you can use:
#    Option "XkbModel"    "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#    Option "XkbLayout"   "de"
# or:
#    Option "XkbLayout"   "de"
#    Option "XkbVariant"  "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#    Option "XkbOptions"  "ctrl:swapcaps"
# These are the default XKB settings for Xorg
#    Option "XkbRules"    "xorg"
#    Option "XkbModel"    "pc105"
