Looking at this in more detail, from
(http://test.winehq.org/data/daafda22f840edc9a584abc7925f9ee17ef18228/vista_APetaccia-NXbitSet/ole32:marshal.html):
marshal.c:2337: Test failed: "CoUnmarshalInterface" failed with
error 0x80040154
marshal.c:2340: Test failed: Number of locks should be > 0, but actually is 0
test failed: timed out
on my current setup, I get the first two, but the test crashes. This
may be because I have SP1 installed which makes it like the 2008
results in most cases. This is backed up by the results at
http://test.winehq.org/data/a0289148e14728e45587b8cb17f90862d8400939/,
where there are Vista, Vista SP1 and 2008 test results.
NOTE: 0x80040154 is "class no registered", so I suspect that this is
due to the IWineTest interface not being registered.

The test_marshal_and_unmarshal_invalid test in marshal.c has a similar
check (line 405), so there is already a presedence for this.
