A few hours after the previous post I got to a known WiFi hotspot and managed to get the Macbook to download the Internet Recovery image. I sucessfully reinstalled Lion on a formatted Volume.
I've spent the day selectivly restoring the system, I didn't want to do a full Time Machine restore incase a setting I had previously set was causing the crashes. I created a new account and restored Applications, Other files, and User accounts; then copied documents out of the old account. I'm using a fresh ~/Library/ .
At 18:06 the system froze again. The console shows nothing unusual, as if the power&battery were abruptly disconnected. I was not activly using the laptop at the time, Photoshop was open but I was not using the keyboard or mouse.
Incase it makes any difference, I'm using Filevault.

On advice from an ExpressLane call I sent the machine to a Premium Reseller in Dublin on Wednesday. They ran looped hardware tests for 40hr+ and within the last hour the machine froze. They rang me to say that it was a logic board error and a replacement has been ordered.
Unfortunately they wouldn't give me the error code, or what the cause of the problem was (CPU, RAM, northbridge, &c.).

I got my MacBook Air back on Tuesday. It has a new Logic Board. It hasn't crashed since the board has been replaced.
However, it now has two new problems: Wi-Fi & the Mini DisplayPort.
WiFi first. I'm not the only person with this problem. This was the 802.11 (Wi-Fi) adapter specs from System Information:
Card Type: AirPort Extreme (0x14E4, 0xE9)
Firmware Version: Broadcom BCM43xx 1.0 (184.108.40.206.18)
A ping to my home router looks like this:
That's when I can actually associate with an access point. I could not connect to the AP in work, a Motorola Netopia Model 2247-62 with WPA2.
I re-installed Lion, no luck. I followed Maayan's guide to downgrading my wireless drivers and I'm now able to connect to this Netopia AP, most of the time. Earlier it would not connect and console showed the following:
Dec 1 15:38:48 localhost kernel: AirPort_Brcm43224: Ethernet address 04:0c:xx:xx:xx:xx
Dec 1 15:38:48 localhost kernel: AirPort: Link Down on en0. Reason 8 (Disassociated because station leaving).
Without rebooting this problem seems to have fixed itself.
Ping responses from the router are better, I'm only getting ~7% packet loss:
For reference, this is not a problem with the router, my friends MacBook Pro shows the following ping response over the same time period, at the same distance from the router:
The monitor I tried using was a Dell E171FP. When plugged in OSX Display preferences can see it. It worked for ~10 minutes and then went into power save mode. After unplugging/connecting and rebooting it remains in sleep mode.
I have tried plugging the monitor into another Mac (same VGA-MDP adapter) and the monitor works with no issue. I've turned off display sleep in Energy Saver preferences, no joy. I'll try another monitor later.
Minor (and humorous) side point, OSX no longer knows what my Serial Number is:
