bigraceusademo.exe on wine 1.3.26 (no debug channels)

In the Big Race USA Demo (or the full Big Race USA game as sold by gog.com),
the menu animations (blinking of text and spinning of icons) move far too fast.
Additionally, the game music and sound effects are incredibly fast and
'crackly'. I mention both issues as it seems likely they have the same root
cause. My CPU is an i5-750 at 2.67Ghz (presumably this problem may not occur on
something much slower like an Atom).

Workaround: Use cpulimit on the bigraceusademo.exe process. Turning on a noisy
enough debug channel will also slow the process down enough that the sound
problem will go away.

To reproduce, just install the linked demo, run bigraceusademo.exe and observe
the rapidly spinning menu items and corrupted audio output.

$ sha1sum bigrace.zip

The demo and full game both work perfectly in Win 7 x64 on the same hardware.

I tested in wine 1.0.1, 1.2.3, 1.3.26 and some versions in between. The problem
was less pronounced in 1.0.1 (likely due to worse overall performance).

I'll attach the output from 1.3.26, though the only relevant line appears to be
the following, which seems to be a likely culprit for the problem:

fixme:ddraw:ddraw7_WaitForVerticalBlank iface 0x1557b0, flags 0x1, event (nil)
stub!
