PC386 BSP vs. paranoia - unable to run prerelease

  This is exactly the problem I am experiencing now with the the 
prerelease. It is stopping at the exact place in the pc386 build.
(Note that this is not the pc386dx build - it also does not work, but 
paranoia does for it)  Strangely, the pc386dx paranoia is passing.

The behaviour is identical on the sample from the build on all three 
host development platforms: OSX, linux, and cygwin

Is anybody else having trouble running the samples?

What ended up happening here? How did this get fixed?
