It looks like sound modules are getting plugged okay. But a module not in
the 2.4.20 list which appears in the 2.4.26 list is 'r128'. I believe
this is a video module (I'm running with a ATI Rage Pro video card).

I thought my configuration was essentially the same as a stock RH kernel,
(copied from their configs directory of their kernel source). Digging
into the r128 module, it looks like it's aimed at DRM (direct rendering),
and that may be what mplayer doesn't like. And apparently, (via google),
there's a problem with mplayer and DRI and (maybe just) ATI.

Now... to figure out how to fix it. (I'll take a look at the "help" in
the kernel config.)
