[ltp] Thinkpad R40 mic input and phantom power

[Ben Pearre]

I know, I should call IBM or Intel, but I like you guys better :)

Any idea whether the R40's soundcard supplies "phantom power" to the
microphone jack?  Or whether ALSA lets you control this?

I've searched forums, and I haven't found mention yet of a laptop
soundcard that does do phantom power, but I'd rather not damage my
mic.
