Hi again!
I confirm that this "old stuff" :) works on RB450G. Web document should be corrected to use port 280 for downloading patches from http://loos.no-ip.org.
I also made some corrections to gpio.diff as world failed to build because of warnings in gpioctl.c . You may see corrected diff attached.
I will now make some tests on the board and give you feedback if everything is fine.

Here is my dmesg.boot:

Now, tell me how can I help you with writing some code for ethernet switch etc? As I need to get it working :).
