Select between V1 and V1.5 in kernel_menuconfig under machine selection -> board support.
The patch:
Trunk: (Attitude Adjustment)
hhpatch.zip
Drop it in "target/linux/brcm63xx/patches-2.6.39"
Backfire:
patch_backfire.zip
Drop it in "target/linux/brcm63xx/patches-2.6.32"??
To flush old changes and apply the new patch,
make target/linux/{clean,prepare}
Heres my configs. It should provide a good starting point. Note, the openwrt ip address will be 192.168.1.11

Installation
When you have installed redboot and power cycled the router, you should be able to either,
Log in by telnet to 192.168.1.11 9000. You could set things up from here but the configuration values set here (ip, mac) will not be read by openwrt anyway. You can still load and flash firmware images here.
Hold the wireless button while powering up. Redboot will then attempt to load a script called "factory_script" from the root of a tftp server at 192.168.1.100. The script contains commands to create the filesystem, download firmware images from the tftp server, and write them to flash. When entering factory mode the upgrade led turns orange then to red or green depending on whether the script was found.
The following script will create a "factory script" specific to you firmware image. You can use it two ways,
When you have finished your openwrt compile, just put it in the root of your tftp server, point it towards your openwrt trunk base directory eg, ./mkfscript.sh/home/user/openwrt/trunk. It will take the needed parts from openwrt, move them to the same directry and create "factory_script" to fit.
or,
You can place the two needed files: gzipped linux kernel named "vmlinux.gz" and a squashfs filesystem named "root.squashfs". Run the script with --use-current parameter and it will create "factory_script".

Notes:
1, Openwrt is set up by default to use ethernet port 1 as wan and port 2 as lan. Telnet is not allowed on the wan port. Plug your cable into ethernet 2.
2, If you have flashed a firmware image that wont boot, don't worry, you can always load a new kernel by holding the wifi button while powering up the hub.
3, Still no adsl driver.
Here's a couple of precompiled images with script for tftp installation.
Let me know if there's anything missing or any other problems.
