Starting brltty on edgy ubuntu-powerpc

[Cheryl Homiak <chomiak charter net>]

Dave Mielke thinks my problem with question marks on the braille  
display when I try to start brltty using my usb-to-serial cable with  
the powerpc live cd may be one that has been resolved in the latest  
repository version of brltty. But he suggested that instead of trying  
to modify the iso i'm using I try using nofb in the boot parameters.  
would I do

ubuntu nofb
at the boot prompt. Also is there any way I can know for sure that I  
am at the boot prompt?

Tia.
