Yes, I checked out the web site again. Some interesting text from there
follows. Looks like SDL does a lot of the abstraction for us, and is
very flexible:
Q: How do I choose a specific audio driver?
A: You can set the environment variable "SDL_AUDIODRIVER" to the name
of the driver you want to use. The drivers available depend on the
platform and SDL compile-time options:
Linux:
dsp - (default) Use the OSS API by opening /dev/dsp
dma - Use the OSS API to perform DMA access on /dev/dsp
esd - Connect to the ESound audio daemon
Win32:
dsound - (default) Use the DirectSound API
waveout - Use the Win32 MultiMedia API
Q: How do I choose a specific video driver?
A: You can set the environment variable "SDL_VIDEODRIVER" to the
name of the driver you want to use. The drivers available depend
on the platform and SDL compile-time options:
Linux:
x11 - (default) Use the X11 windowing system
fbcon - Use the framebuffer console
svga - Use the SVGAlib API
ggi - Use the General Graphics Interface API
aalib - Use the Ascii Art library
Win32:
directx - (default) Use the DirectDraw API
windib - Use the standard Win32 GDI

Sure, at any point you can put the mods on the 'net and post a URL. If
they're small enough, post 'em here.
