After carldani gave me some hints on irc, i'm currently blaming the 
flashchip itself. I think the support for the w39v040b has regressed in 
the last 13 months, after it was set to TEST_OK_PREW in commit 252.

Dan, apparently you then said it tested ok (and i hope this is your 
correct email address). What board were you using this rom on and can 
you test a recent svn version of flashrom?

Thanks,
