I just did the experiment of building xorg-server with the hal useflag *off*, and
found that neither keyboard nor mouse worked until I restored the two InputDevice
sections that I commented out when I switched to evdev+hal:

Section "ServerLayout"
     Identifier     "X.org Configured"
     Screen      0  "Screen0" 0 0
     Option         "AIGLX"        "false"
     InputDevice    "Mouse0" "CorePointer"      <------ restored these two lines
     InputDevice    "Keyboard0" "CoreKeyboard"  <-------
EndSection

Section "InputDevice"
     Identifier     "Keyboard0"
     Driver         "evdev"
     Option         "Device" "/dev/input/event3"
EndSection

Section "InputDevice"
     Identifier     "Mouse0"
     Driver         "evdev"
     Option         "Protocol" "auto"
     Option         "Device" "/dev/input/event4"
     Option         "Emulate3Buttons" "True"
EndSection

Note those "Device" entries.  I found those devices in /dev/input/by-path/:

$ls -l /dev/input/by-path/
lrwxrwxrwx 1 root root   9 2010-05-16 10:40 platform-i8042-serio-0-event-kbd -> ../event3
lrwxrwxrwx 1 root root   9 2010-05-16 10:40 platform-i8042-serio-1-event-mouse -> ../event4
lrwxrwxrwx 1 root root   9 2010-05-16 10:40 platform-i8042-serio-1-mouse -> ../mouse0

"evdev" uses "event-devices", hence the name.  I don't use the mouse0 device at
all but I'm guessing I would if I used the "mouse" driver instead of "evdev".

Starting with xorg-server-1.8 the mouse and keyboard Inputdevice sections are no
longer needed (not sure about synaptics, though), because the server uses evdev
automatically (no manual configuration like cited above) and ignores hal completely.

Using the evdev driver alone, and xorg-server built without hal, I get this:

(**) Option "CorePointer"
(**) Mouse0: always reports core events
(**) Mouse0: Device: "/dev/input/event4"
(II) Mouse0: Found 9 mouse buttons
(II) Mouse0: Found scroll wheel(s)
(II) Mouse0: Found relative axes
(II) Mouse0: Found x and y relative axes
(II) Mouse0: Configuring as mouse
(**) Option "Emulate3Buttons" "True"
(II) Mouse0: Forcing middle mouse button emulation on.
(II) XINPUT: Adding extended input device "Mouse0" (type: MOUSE)
(**) Mouse0: (accel) keeping acceleration scheme 1
(**) Mouse0: (accel) acceleration profile 0
(II) Mouse0: initialized for relative axes.
(**) Option "CoreKeyboard"
(**) Keyboard0: always reports core events
(**) Keyboard0: Device: "/dev/input/event3"
(II) Keyboard0: Found keys
(II) Keyboard0: Configuring as keyboard
(II) XINPUT: Adding extended input device "Keyboard0" (type: KEYBOARD)
(**) Option "xkb_rules" "evdev"
(**) Option "xkb_model" "evdev"
(**) Option "xkb_layout" "us"
