sound is broken in Maverick apps that rely on OSS

[Rocko]

Since Maverick ships without OSS modules in the 2.6.35 kernel and therefore /dev/dsp does not exist at runtime, various applications that rely on OSS exhibit broken and undesirable behaviour, eg:

* Alien Arena segfaults during sound initialisation ((I tried version 7.45)

* wine apps like Torchlight and Age of Empires 3 have no sound, and there are no errors indicating what the cause might be

A workaround is to run the application using padsp (eg "padsp ./crx" for Alien Arena and "padsp wine Torchlight.exe").

I guess it is an intentional decision to deprecate OSS: if so, the problem is that the reason behind these crashes/lack of sound is not all all obvious to the casual user. Perhaps an entry in the Ubuntu release notes noting that some applications that rely on OSS will be broken and detailing the padsdp workaround would be useful.

This is a consequence of "fixing" bug #579300
The fix at the moment is to reconfigure and compile your own kernel, undoing the damage.
