newer linux kernels should support most of the controllers on these cards...
I would go ahead and try to install linux on this system before i got a new board. I think there is a good chance the os is corrupt and maybe just install linux on it and get a better nas in the end anyhow.
I would have used a wrt54g with openwrt or tomato installed on it. I can use the web interface on my wrt54g running tomato over the interweb using dyndns handled by the router. Then I can send magic packet to my server or desktop using my router interface. 2 minutes later the pc is on and it...
