Hi
If you see the specification, Desknote use SIS System On Chip and combined it with Intel CPU.
http://www.digit-life.com/articles2/ecs-desknote-p4/"SiS® 651 & SiS® 962, 4X AGP bus interface, supports host bus at 400MHz"
Perhaps the module can use similar PowerPC 405 SOC from AMCC / other vendors with built in memory controller, Graphics, Sound, Ethernet, USB, Firewire, PCI-E etc. Perhaps there will be external PCIe port /connector for connecting the laptop to external PCIe based peripherals / docking station.
There is a new SOC from IBM and Sanyo based on PowerPC 405:
==============================================
The 405 was codeveloped with Sanyo in a core-sharing relationship; of the 25 intellectual-property (IP) blocks within the core, six are from Sanyo. At the SOC's heart is the PowerPC 405B3 core, featuring a 192-MHz 405 core, JTAG, MMU, a 16-Kbyte instruction cache and 8-Kbyte data cache. A laundry list of features is also included: a 3-channel ISDN interface; an LCD controller capable of 32-bit color, XGA resolution, and support for TFT and STN displays; a serial port for an audio codec; I/O pins; a smart card controller; and USB, IrDA, parallel and UART ports. The 5.2 million-transistor 405 core pushes an estimated 292 Dhrystone MIPS, and requires 5.2 million transistors in 0.25-micron CMOS, while totaling 57 sq. mm in size. It is estimated to draw 1.4 watts.
