Here is a summary of a successful install of Debain Lenny (Stable) on an Asus Z62J Laptop. The laptop's generic specs are here. So with added CPU, Wifi, RAM and Hard Drive the present configuration is as follows:

• CPU: Intel Core2 Duo 1.830GHz(T5600) w/2MB L2 Cache
• RAM: OCZ Dual Channel 667Mhz (2GB kit)
• Wireless: Intel/PRO 3945 Wireless 802.11(ABG) WiFi Card
• Hard Drive: 250GB Seagate Sata Hard Drive
• Optical Drive: Dual Layer Super Multi DVD-RW/CD-RW Drive
• Graphics: nVIDIA GeForce Go7300 w/Turbo Cache; 125MB dedicated VRAM
• Connectivity: Built-in 56k V.92 Fax Modem; Gigabit Ethernet LAN; Built-in Bluetooth 2.0, IEEE 1394 & 4 USB 2.0 Ports
• Power: 6-Cell Smart Li-ion Battery

Here is a summary of what works and what doesn't:

Component	Status	Comment
Sound	Works	Unlike Etch with Lenny the built-in mic and the external mic jack did not work. See here for details. Everything else was fine
Camera	Works	Just do apt-get install gspca-modules-xx-xx-xx where xx-xx-xx is your kernel version mine was apt-get install gspca-modules-2.6.26-2-686
Wi-Fi	Works	This is just a matter of ensuring that the firmware-iwlwifi package is installed: apt-get install firmware-iwlwifi
Bluetooth	Works	Very convenient feature see this to configure it
Touchpad	Works	Right out of the box. No configuration needed unless you want two finger right click and scrolling: see my xorg.conf file below
GeForce Go 7300	Works	With or without Nvidia drivers from their site which I installed without a hitch as per these instructions. I then installed compiz-fusion which works very well in Lenny as per these instructions. See my xorg.conf file.
Modem	Untested	Don't use dial-up though as far as I'm aware there are no open source or free drivers for the Z62J's modem
Suspend/Resume etc.	Untested	Will check this out when I get a chance
