In case it doesn't boot from USB Bro.Tiag did write a how-to make use of a CD (you put grub and a kernel on the CD, if i recall correct). That would be quite a bit of work... so in that case it's different (I wouldn't say "hey, just use a stick" and give you trouble and headaches and that. I like easy solutions. But, theoretically, it would work.)
BTW: i did a short search and found this:

Not sure what that means for your question. Just a short hint. I guess someone will be able to tell you.<!> alsaconf was removed from alsa-utils at 1.0.17-1. From the package changelog: "The only valid use-case for alsaconf is aiding the configuration of ISA sound cards."
