Wow. Just installed Ubuntu (daily ISO) on the iMac DV SE. It all just works. Sound is auto-configured, X is auto-configured (like everything!), nice 2.6.8 kernel, mouse button emualtion works out of the box. smbfs isn’t installed by default, it lacks MP3 support (doh, all sane distros do), but everything about it and its GNOME integration make it very clean. Interesting to note that Epiphany isn’t installed, but Firefox is the default browser! Apple Pro keyboard is a little weirdly configured, anyways, Bugzilla.ubuntu has seen some of me.
