David,

Thanks for the new script.  This works for me with the 2.6.37-rc1
kernel.  I don't have the problems with compiz when using the
Intel driver and sound that you report, with that kernel.

Re. the sound problem -  is the device detected properly?

Have you tried running 'alsamixer -c0' in case it's a volume
initialization problem?
