You may need to set up a control file for ALSA (/etc/asound.conf) to
tell it which speaker is which.  ALSA configuration is a pain, but
this problem has come up a number of times on this mailing list, so if
you can find one of those posts it should tell you how.  But first I
would just look at the /etc/asound.conf on your 0.27 disk and see if
you can just copy that.

An Ion CPU is unable to do modern video without using the GPU
acceleration.  So you do need the Nvidia drivers installed and VDPAU
set up to use them.
