No accessibility In Lucid Netbook Edition!

[Dave Hunt]

Since I cannot get an accessible startup from the bootable Lucid usb key I made, I deceaided 
to have my partner do the install.  When it finished, he restarted the machine and logged in.  He started orca 
from the run dialogue, and went through talking setup.  He chose to log out at the end.  It is now 
impossible to log into  this machine.  When typing the correct username and password, the dialogue just 
comes back.  When typing the wrong pair, we get "authentication failure", as we should do.

Besides putting Windows or another distro on this netbook, How can I make it usable again?
