Description of problem:
have tried to boot Fedora-11-{alpha,beta,snap1} but does not manage to get system booted. After SYSlinux message a grey screen turns up with no message or picture in it.

If ESC is pressed a boot prompt shows up (any hint on what to fill in here ? i have been unsuccessful this far)

If any other key is pressed something along the lines of "TAB for alternatives" comes up but nothing happens when pressing tab.

Version-Release number of selected component (if applicable):
F-11-{alpha,beta,snap1}-liveimage.x86_64

How reproducible:
every time

Steps to Reproduce:
1. boot from said live image (present on a USB key)
2.
3.
  
Actual results:
grey screen, no progress

Expected results:
i wanted to make sure that the NOUVEAU driver works for my setup in F11

please excuse me if i am too clueless for my own best, if i have filed this bug on the wrong component, or if i have provided unsufficient data (of which i can try to be helpful) 

i have tried a few different images {alpha,beta,snap1} and a few different USB hardware units
