add support for Vibra16X, OPTi925, and bring in several assorted
fixes to the code and documentation.
Also present here are apm hooks so that laptops can properly
reconfigure the hardware after suspend (tested on the Libretto50).

changes:
o rip the old select from his distribution to prevent extra pollution
o the code now uses audio dma, helps reduce clicks
o improved card support, should work in full duplex on sb16 cards
o add better voxware ioctl support pointed out by Joao Carlos Mendes
Luis <jonny@coppe.ufrj.br>
o remove an unused file that I included for more complete history
o and MANY other changes
I have personally tested this code with a CS4237 based card and an AWE32
(non-PnP). Both cards worked fine in 8bit and 16bit mode.
