[ltp] USB flash card reader

[Joel Ebel]

I doubt it is a hardware issue with the thinkpad, but I suppose it's 
possible.  If you boot knoppix on the thinkpad does the card reader 
work?  If it doesn't then it's probably a hardware issue.  If you give 
some of the details requested we might still be able to figure this out.
