You are using a very old flashrom version. Please use at least 0.9.1
(this will give better error messages) or latest code from svn (this
might will tell you exactly what's wrong).

This message means that probing for most chips is not possible because
the BIOS has forbidden the classic probe command.

Interesting. I wonder whether these messages appear even with latest
flashrom from svn.

Try very latest flashrom from svn. I think it will not find your chip,
but "flashrom -V" will tell us if there is a chance to get it working
for you.
