Ok, my X server starts now. 

When I try to switch to a virtual text console, my screen blanks.  I
can still execute a shutdown command blindly.  This implies the kernel
hasn't locked up.

There must be some conflict with the VGA controller still?  Maybe the
work around to fix the dead console at boot?
