GigE support for 440GX is in official 2.6. Patch for 2.4 is available 
at http://kernel.ebshome.net. If you don't feel comfortable dealing 
with kernel patches, I'd recommend 2.6

Effective Ethernet throughput highly depends on packet size. For some 
small packet sizes 600Mb/s is theoretically impossible over GigE.

I achieved 900+ Mb/s TCP throughput with my driver (packets around 4K 
long) and using sendfile(2) based test application.
