This chip is a Merom Intel Core 2 Duo processor. It's a dual core with 4096 KB of unified cache L2, offers a complete x86_64 instruction set and includes an NX bit (Intel calls it XD bit, IIRC). Two generations ahead of the Pentium M, but still similar. The first iteraction of the Intel Core Duo CPUs (codenamed Yonah) were roughly just two Pentium M cores on the same die with a common cache L2. Clever but not innovative. Core 2 Duo chips are a major improvement over the Yonahs but nothing innovative.
A comparison between the Pentium M Banias 705, the Pentium M Dothan 750 and the Core 2 Duo is shown on the table below:

The battery runs out in almost 6 hours when the computer is idle (meaning noone is doing anything with it) using frequency scaling to cut down CPU and chipset power consumption. Normal usage drains the battery in about 3 hours which is well within the Centrino territory. Heavy usage drains it in about 1h-1h30 (linux kernel compilations or dvd burning, etc).
The battery on this laptop is a standard Control Mode battery, which means that the kernel can read reliably the battery state/status and the AC adapter state. Many graphical and text daemons currently monitor this information so no issues here.

Marvell Yukon 2 Gigabit 10/100/1000 Base-T is the name of the PCI-Express integrated ethernet controller. The best driver for this card is the sky2, although the older skge works as well. Selected under the Device Drivers - Network device support - Ethernet (1000 Mbit). For the sky2 driver, the option to select is SysKonnect Yukon2 support while for the skge it's the Marvell Yukon Chipset / SysKonnect SK-98xx Support in the kernel configuration tool.
Support for this PCI device [11ab:436a] was included in kernel version 2.6.21. By looking at the diffs, the driver itself did not change much - only the detection routine was changed to support this new id.
Modules: sky2 or skge

This MacBook Pro contains a wireless card based on the Atheros AR5008E chipset. Like in most other wireless NICs, this chipset is composed of an AR5133 802.11 radio chip and an AR5418 MAC/baseband processor module. The radio module is autonomous and handles the electric and radio work (both (de/)modulation and reception/radiation of the radio signal, along with any other signaling involved). The MAC module works at the link layer and interacts with the operating system through the PCI-Express bus to its respective driver.
Support isn't perfect but we're getting there. As far as I know, three (3) drivers may be used to handle this card, with the last (ath9k) likely to be the best one.
