need help installing to a USB stick

[Technomage Hawke]

My roomate just handed me a 8 GB USB memory stick. He wants me to install a fully operational Ubuntu 11 system to it. unfortunately, all I have is a vinux install dvd and a mac. since the Ubuntu install doesn't have speech or braille support enabled at startup, I find myself in a position of needing some help. 

I am at a loss for the first time since I started using linux. Also, this is the first time since using linux that I have forced to use it totally blind (before I was merely just a very low partial using very large print). since going total last year, I have found doing some things (like computer tech support) a lot more difficult.I know that vinux is ubuntu based, but it doesn't include support for KDE (which is what the room mate wants).

anyone have any suggestions or help they can offer?
