I'm running Lucid Linux with Xoscope and Osqoop on a Gateway PA6. All you need is to download the Lucid Live CD ISO and burn it and boot from it, then get online and download the scopes.
The trickiest part (but hardly difficult though) is to make a small passive circuit with caps and resistors to divide down the signal voltage and block the mic DC power coming out of the laptop mic port.
It will work with just about any reasonable signal voltage, given the appropriate voltage divider. The limitation is the 96KHz sampling frequency. The upside is that it will store hours and hours of data (limited only by available disc space).
