Added a note about OPTi 82C929 based cards.
Clarified GUS DMA Settings.
Other misc. changes.
This should hold us over until I can finish cleaning up TASD, and finish
reintegrating all of the FreeBSD changes to the sound driver. At that time
this document will be removed, and it's information moved to the handbook.
