It looks I am conversing with myself but I will not filing bug
reports after all.  At least not for now. :-)  Various troubles
I run into seem to be quirks of that particular machine.

First it looks like that if there are some changes in a driver
(different binaries or maybe settings; in particular I tried "vesa"
both with XFree86-4.3.0-2 and XFree86-4.3.0-5) then one is loosing a
picture until the whole thing is rebooted.  Sounds like some video
re-initialization is missing or failing, with BIOS eventually
restoring some sanity, but I have no idea what may be really
responsible.  Nothing wrong shows in log files, as far as I can see,
but no picture without a reboot either.  Some situation seem to be
more prone to cause that but I really cannot put my finger on it.

This I tracked to BIOS too.  This graphic chips apparently "steals"
a memory from a system and in "Advanced" BIOS options there is
something with an non-obvious name (IUW?, IUG?) and two
possibilities "1M" and "8M".   The first one is a default and it
really means something between 800 and 900k. With it you will see
for 16 bits:

With BIOS set to another one the driver grabs all memory it
needs and 1024x768 with DRI works both in 16 and 24 depths.
'glxgears' in 16 bits and with a default 300x300 window reports
around 875 frames per second.  Surprises, surprises ....

But why tuxracer is silent with sound otherwise working so far
I have no idea. :-)
