What do those EFI updates specifically do? I read the short description but would like a more detailed info.

That's not Apple's style. I bet it "Improved capability with current generation models". Or something super vague like that😀

I beg to differ - reinstall without first erasing is what the OP said he did.
my suggestion was to wipe the hdd first then reinstall OS X.
agree it is more than likely a hardware issue, but the one issue of repeated 'kernel panic' I had on this 2011 Air was resolved by my suggested method.
he's still better off to contact Apple direct by phone and if he lives away from a store then post is the only option.
it seems unwise to me to persist with self-fixing if the thing is still under warranty.
send it to the doctor

Nevermind what i said about iStat Menus/Wifi. Mine froze three times this morning without either. I think i'm just going to give up and take a hammer to this thing.

This is something that might give you a clue as to what is happening. If you have an external hard drive, install on it a clean install of 10.7.3. Create one admin user on the external 10.7.3 install. Don't install any third party software on the external 10.7.3 install. Boot to the external hard drive and see if you still get kernel panics.
I have a clean install of 10.7.3 on a external hard drive. I use it to diagnose problems that may occur with my computers. What this helps me do is isolate any installed software as the cause of an issue.
In regard to the OP, if after trying the clean install on an external hard drive and you still have kernel panics then you probably have a hardware issue. I say this as I also have a 2011 27" iMac and have not yet had a single kernel panic since clean installing Lion.

FWIW I and many others have been having the same problem. Mine is a 27" 3.4ghz iMac with SSD and 16GB of RAM.

If you search for "lion wifi kernel panic" the top hit is this long thread with many, many people suffering the same problem:

Including schools with multiple machines impacted. The only solution appears to be to disable Wifi and use a cabled connection. I have tried a complete clean Lion reinstall and the problem remains.

graemerocher,
I read through the Apple support forum and link and it seems people are thining that it is software not hardware related. Since I have the exact same machine as you I think there is more then a software issue happening, in regard to the kernel panics. Maybe there is a different batch of airport cards that are slightly different which don't like the Airport driver. I would definately be on the phone with AppleCare for this one.
