Could you please double-check that the !lsi53c895a case works fine, too? 
(just temporarily change it into a "if (1) { ..." statement) ... I'm a 
little bit afraid that the TAP protocol might be incomplete without the 
g_test_run() at the end otherwise. If so, you might now need a "goto out" 
instead of the "return 0" here...
