There's no need for an ALSA->OSS layer. The flashsupport lib has direct
access to the sound buffer.

You need to make sure the flash plugin can load the support lib
though, because it fails silently. Can it find all lib dependencies
for instance? What does ldd say:

% /compat/linux/bin/sh /usr/bin/ldd /usr/lib/libflashsupport.so
