Works perfectly under every distro I've thrown at it. Only thing that doesn't work is the onboard WinModem, but that's pretty much par for the course these days. If you're running an older XFree than 4.2.0, you'll have to use the FrameBuffer driver as the Cyberblade driver won't work properly.You'll also need to ensure that LILO boots Linux with the framebuffer enabled and set to the correct resolution. Under 4.2.0, everything works fine, and none of this is necessary.

With SuSE 10.0 everything including the onboard modem of my Toshiba 4600 worked right out of the box for me. However I couldn't get the modem working with SuSE 10.2 (I didn't try very hard, I just went back to 10.0).
