Ok, that wasn't hard 8-)

The machine now boots with the monitor connected and continues to run 
correctly when keyboard and mouse are plugged in.

With monitor, keyboard and mouse connected it still spits out a stream of
Timeout poll on interrupt endpoint
Timeout poll on interrupt endpoint
....
during the boot process. The spew seems continuous, but when I typed
boot
into the spew, it looks as if the kernel took over and the machine is
now multi-user. 

Evidently it got stuck in loader, the boot command got it unstuck and
after that all is normal.

So, I guess the video issue was a distraction that's now fixed. The 
problem with USB mouse and keyboard remain unresolved but nonfatal.  

Thanks _very_ much for your help!
