I did some more analysis on this:

Audiosurf calls wined3d_device_get_display_mode with a swapchain_idx of 0. In
current wine, this means that the returned hr will be uninitialized, and the
mode structure left unchanged - so there's garbage in there (I added a FIXME to
get these values):

fixme:d3d:wined3d_device_get_display_mode device 0x146a80, swapchain_idx 0,
mode 0xda80ac, rotation (nil).
fixme:d3d:wined3d_device_get_display_mode hr 4, Return width 14348384, height
14348216, format_id 98596972, refresh_rate -2147467259

Interesting enough, just removing the if (so that swapchain 0 is properly
queried) does not fix the issue even though the data looks much saner:

fixme:d3d:wined3d_device_get_display_mode device 0x146a80, swapchain_idx 0,
mode 0xda80ac, rotation (nil).
fixme:d3d:wined3d_device_get_display_mode hr 0, Return width 1366, height 768,
format_id 115, refresh_rate 60

I am still experimenting to come up with a minimal patch fixing/working around
the issue locally.
