could someone post the fcc id or high resolution pcb pictures? i have a WRT54G2 with atheros chipset but 4 mb flash and 16 mb ram. i can also port a 2 mb flash device if it has 16 mb ram. _________________ one cigarette costs 2 minutes of your life.

I cracked open a V1.5 unit and the contents are:
Atheros AR7240-AH1E E47132 1B 0910 Taiwan
Winbond W9412G61H-5 0924H 69103P50001
There are two header traces one:
J8 14 pins and a square (presumably pin 1)
J5 is just below J8 5 pins again with a Square trace
around a via (presumably pin1) this goes to the Atheros chip according to the traces that I can see.
Hope this info helps the effort. I took some pics too. I will try to upload those shortly. :D

If someone can direct me on the Jtag connections (if it is one) I will be happy to get a dump or whatnot.
I have a parallel jtag cable that I cobbled together that worked for the older 54g units.
This page might be of help in finding the JTAG port. Looks like a little soldering is required; only the pads (no header) are on the logic board as it ships from the factory. While the photo is of a rev 1 Broadcom logic board, it’ll give you an idea of what to look for, and may still be in about the same place on the rev 1.5 logic board.
[Note: the JTAG connector is on the edge of the board; the 5-pin connector to its left is a serial port.]
First off, Brainslayer, you're awesome. Second, I picked up a v1.5 router for Christmas and snapped a bunch of hi-res pics of the board and WiFi. This seems to be the most dominant reversion board selling at major retail chains, atm. From what I can ascertain, the chips are idenified as follows:
Atheros AR7240-AH1E 400Mhz cpu
Atheros AR9285-AL1E WiFi controller
16MB Winbond W9412G6IH-5H DDR ram
2MB Winbond 25Q16BVSIG flash (next to JTAG)
Let me know if you need any more/better pics of this board, it would be really nice to have DD-WRT on it. I also have a JTAG cable (DLC5) if you need a dump of anything, just need to know what the pinouts are on the board.
