Hello.  It doesn't appear to be qt opengl-related.  I have the qtgl libs 
installed on both system, in any case.  I have also done a search for the 
libqgl files and they exist in the qt2 directory (I also set the 
QTDIR=/usr/lib/qt2 variable before trying to build 3dom.   It finds the 
proper qt libs and doesn't complain during configure).

As for the ac97 sound thing, it is solved and working.  Whatever the problem 
was with the two pci soundcards I tried (AudioPCI and SB PCI 128), it doesn't 
exist for the ac97  - no strange static.

It took loading (via modprobe) snd-card-via686a - this loads a host of 
modules - and then loading snd-pcm-oss (without this one, it doesn't work).  
Then not only changing settings for the alsa mixer (via either amixer or 
alsamixer), which is not enough, but also unmuting everything.  Saving the 
new settings with alsactl (requiring an "alsactl restore" after every 
reboot)...THEN sound works fine.  What a pain.

The ASCII graphic alsamixer doesn't, apparently, allow for unmuting, just 
setting the levels.  You can do it all with amixer with a little more effort 
- and in any case, you will have to use amixer anyway to unmute everything. 
Points:  if alsa is going to be the default sound system for Mandrake, then 
it needs to install in an UNMUTED state AND have the mixer settings set to, 
at least, a midrange level across the board so sound works right off.  It 
would also be nice to have a graphical kde/gnome, etc, frontend to amixer 
that handles everything - unmuting and muting included.  Alsa is too much 
trouble out of the box for many/most new users.  I am not a new user, but 
alsa is still a pain to setup when it is entirely unnecessary.
