I consider the behavior of these GPUs generally broken, but at least one format is working on all of them. We just don't know in advance which one, and on at least my Geforce 9 an actual game is broken too. This test accepts a few known failure conditions as broken, but expects at least one format to pass in ddraw2 - ddraw4. ddraw1 only has D16, which fails on GF9, so don't even attempt to run the test.
I previously seemed to have results with "reversed" 32 bit formats (S8D24/X8D24 instead of D24S8/D24X8), but I could not reproduce this any more today. I suspect I did something wrong with adjusting the expected results for the shifted depth mask. --- dlls/ddraw/tests/ddraw1.c | 12 ++++++++++++ dlls/ddraw/tests/ddraw2.c | 16 ++++++++++++++-- dlls/ddraw/tests/ddraw4.c | 21 +++++++++++++++++---- dlls/ddraw/tests/ddraw7.c | 33 ++++++++++++++++++++++++++++++--- 4 files changed, 73 insertions(+), 9 deletions(-)

broken() statement is redundant.

right, ddraw_is_vendor already takes care of this, I'll fix
