Bitwig[1] is a decent commercial DAW that works on Linux and is very similar to Ableton.

Edit: Not sure about the state of Linux VST plugins/emulation though :)

There's also Reaper[1], from the guy who made Winamp, that has a Linux version in testing[2].

And in many cases, Ardour[3], may be good enough.
