Thanks to everyone who has replied and given some advice to my initial

This log patch would deserve to be part of the release, as it adds a lot
of value to Xorg.0.log.

After some investigations, I have fixed a few stupid things, and the
situation has improved. Nevertheless, I discovered that the whole hal
discovery creates a lot of delay. Taking into account that i have fixes
input devices (touchpad / keyboard on USB, touchscreen on I2C), how can
I disable the hal discovery and hard-code the three input that I have?
Would the following xorg.conf make sense? I'm still confused by
"AutoAddDevices" and "AllowEmptyInput".

Section "Module"
	Load		"extmod"
	Load		"dbe"
	Disable		"dri2"
	Disable		"glx"
	Disable		"dri"

Section "ServerFlags"
	Option		"AutoAddDevices"	"false"
#	Option		"AllowEmptyInput"	"false"

Section "ServerLayout"
	Identifier	"DefaultLayout"
	Screen		"Screen0"
        InputDevice	"Touchscreen0"

Section "Screen"
	Identifier	"Screen0"
	Device		"Device0"
	Monitor		"Monitor0"
	DefaultDepth	16
	SubSection "Display"
		Depth	16
		Modes	"1024x600"

Section "Monitor"
	Identifier	"Monitor0"

Section "Device"
	Identifier	"Device0"
	Driver		"fbdev"
	Option		"ShadowFB" "false"

Section "InputDevice"
	Identifier	"Touchscreen0"
	Driver		"tslib"
	Option		"Device"		"/dev/input/touchscreen0"
