Very easy: open the mach-arv.c located in (openwrt_AA_dir)/target/linux/lantiq/files/arch/mips/lantiq/xway and delete the line 532 or comment it.
At least "worksforme".

this is what i get from the terminal

This log means that the openwrt image you have flashed was corrupted. Very strange.
If the u-boot version that your has tftp and httpd works will be very easy to flash a new image.

What means "up"?

thank you very much
i tried to comment it and re-compile it but it doesn't work when i upload to the router it tell me that i should re-upload an other image from http server

Can you put the bootlog or the dmesg output?

"up" just means that o71 is impatient and doesn't realise that we all have Real Lives that interferes with helping him out.

Try with this image and tell if loads right and if the wifi works.
http://www.mediafire.com/?c9aiivy4gx7j5dj
Once verified that works i can send you a config file or an image or both with the packages you need.
Is very strange that following the guide the images are corrupted; maybe bad luck?

Please, don't tell me Mr. Pteridium; every time i read Mr another white hair Mr. o71.

My english is poor too.

Well, this time fails other thing; a little progress.
I think i've saw this error before, but don't remember the exact cause.
I've put too debug in the image because i was testing something and this is the cause of so much verbosity at the boot.
Can you put your uboot environment? Is very easy: stop uboot and execute printenv when the "ARV4518 =>" prompt appears.
I think that the jffs2 error could be due a misconfiguration in the bootloader.
Also post the bootlog without the jffs2 errors.

P.S.: since revision 36510 of Attitude Adjustment the patch for the arv4518pw has been applied.

Sorry, didn't realized of your post.

The problem is the kernel address. 0xb0030000 is the right value for Backfire and old Attitude Adjustment revisions. For trunk and the latest AA this address must be set to 0xb0020000.
To change it execute the following commands:
setenv kernel_addr 0xb0020000
saveenv
reset

Flash openwrt and, if nothing more happens, enjoy.

You are right: the last partition of the flash (where lies the MAC and the wifi calibration data) is empty or corrupted. No problem, because can be easily "patched".
The link contains a backup of the last partition (if you haven't it) of an ARV4518PW. Simply copy the file in the router and execute "mtd -r write (file_name_and_path) board_config" and wifi working after reboot.
http://www.mediafire.com/?6d1t67pm2b0cm92

The partition backup comes with a mac that begins with 00 22 2D. The mac belonged to a dead router so could be used without problems, but i think it's better change it. With any hexadecimal editor open the file, go to offset 16 a write your router's mac.

Good luck!

I guess I'll try patching rt2800pci so that it thinks it uses a rt3062 instead, no Idea if this is feasible though.

EDIT:
From what i've read/guessed in rt2800pci, the rt3062 and rt3592 are handled the same way and are basically the same chip.
So, the pciid isn't wrong per se and it's also the same as in the  TOH.
As far as I can see most of the frequency and chip capability stuff is initialized via eeprom....
