I just compiled vanilla tomato 1.23 with broadcom drivers 18.104.22.168. (i call it MND "much newer drivers"). The patch for the intel-issue is included. I use this for my 7 WRT54GLs 1.1 which are simply used to extend range in my WDS-System. So no other mods are needed on these devices. I found the source in git repository. It works with no problems since 2 days but it is just for test purposes, so it comes with no warranty. If someone is interessted in this build drop me a PM for the link.
