Having to reboot to test an update makes it painfully slow for testing. Philipp's driver can do this (once the unload bugs are fixed, which I have patches for). -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
