Patch to fix build issues on Mandriva 2006 (2.6.12-12mdk)

The patch to pcm_native.patch may need more fixing, but it works on my
system now.  Not sure when latency.h was introduced to the kernel.
These patches were needed for me to be able to test build my patches.
The HG repository has been broken since before 1.0.13 release (I just
never tested it until recently).

Changelog entry follows:

Summary:  Fix build issues
        
        This patch fixes build issues on older kernels.

Shouldn't this be wrapped in a version check or something?  Devfs has
been removed from recent kernels.

I suppose it could, but what's the point?  If devfs has been removed in
newer kernels, then it won't be defined, right?  Adding a kernel wrapper
would be inefficient, plus it would be harder to contain vendor kernels
that still implement devfs for compatibility.

The configure script checks linux/latency.h and create a dummy
linux/config.h if not exists.  If this doesn't work for you, it means
that something wrong ing configure script.  Check config.log to see
what's wrong there.
