Same deal here. I've got the Asus A7N8X Deluxe, and the default IDE driver is crap for this chipset. Ripping a cd will take about 60-80% of my 2600+, while it only took about 10% with my older via chipset. My Athlon 750 can do it in about 1/8th the time. I tried applying kernel pathes but they just blew up once I booted the new kernel. I also tried the lastest 2.5.x kernel which has some sort of nforce support but it wouldn't compile with that option selected. Neither of the two supplied NIC drivers will work either (running Slackware 8.1), but at least I could put in another NIC. The only thing I got to work was sound. Of course, everything works fine in Windows 2000, so I guess I'm stuck using that for a bit. It would be nice if Nvidia put some amount of effort into making a decent linux driver for this chipset.
