Thilo, I tried it. Amazing! So who owns this driver? I noticed it is called 0.03BETA - it doesn't instill a great deal of confidence in me, I must admit... Though I like the Gentoo stuff, and will probably install it on my workstation, I would prefer to migrate this server slowly through the RedHat cycle, until time to do a major rehack. Where do I get this driver for RedHat or generic kernels?
