--- Comment #109 from P.Panon ppanon@shaw.ca 2010-03-03 19:25:01 --- Although it does look like I missed an update for the card_vendor detection for Gallium. wined3d_guess_card_vendor() should have
if (strstr(gl_vendor_string, "ATI") || strstr(gl_vendor_string, "Advanced Micro Devices, Inc.") || strstr(gl_vendor_string, "DRI R300 Project") || strstr(gl_vendor_string, "X.Org R300 Project")) return HW_VENDOR_ATI;
to properly match an R300 ATI driver with Gallium enabled. However, that doesn't seem to be your problem based on your GL vendor/renderer string values.
