usb ethernet adapters for linux + osx

[Guglielmo Dapavo <alphac@email.it>]

I'm searching for a usb ethernet adapter for both linux and macosx, I've 
found only this one:
http://www.broadbandproducts.com/network_bue.html it seems to have 
support for mac osx 10.2 (but I'm using 10.3 I hope that the driver will 
work) do u know if the chipset ADM8513 is supported under ppc linux?

Thanks
