patch to get sound working in OSS

Bug is still present in GIT after wine 0.9.30, I'm still trying to figure out
why this patch works. To use it, set OSS as your sound driver, disable the
others.

Basically what happens is:
trace:driver:DriverCallback (20008E6D, 0003, 0x8000, 03BB, 00000000, 00000000,
00000000); !
trace:driver:DriverCallback Function (32 bit) !
(which calls 0x20008E6D in WAIL32.DLL)
(which calls SuspendThread)
(which hangs forever)

The patch gets around this by not calling DriverCallback on the WOM_OPEN
message. Is that what Windows 9x does too? Maybe someone with more knowledge of
winmm can help.
