Well thanks for the suggestion, but I checked and I don't have either
of those packages installed. I've attached a zipped up copy of the
entire list for this machine. It doesn't have much installed: just a
base Woody, kde, koffice, kdevelop, quanta - and for Xfree 4.1.0 I
only really installed the base packages.

I tried switching to the Mach64 Xserver from Xfree 3.3.6, which I
thought might make the GL screensavers all work better but instead
even those which had worked slowly ceased to work at all.
I found this comment at http://www.xfree86.org/4.1.0/DRI10.html, which
I suppose may explain the slow GL savers :
=======================< cut >========================
10.4. ATI Rage 128
10.4.3. Performance and Features
While PCI Rage 128 based cards are supported, they do not yet support
PCI GART, so they will not perform as well as their AGP counterparts.
For AGP cards, the AGP mode may be set to 1, 2, or 4. One is used by
default. Higher AGP speeds may result in unreliable performance
depending on your motherboard.
Note that even at 32bpp there is no alpha channel.
The following OpenGL features are implemented in software and will be
slow:
Stencil buffer and accumulation buffer operations
Blend subtract, min/max and logic op blend modes
GL_SEPARATE_SPECULAR_COLOR lighting mode
glDrawBuffer(GL_FRONT_AND_BACK)
Using 1D or 3D textures
Using texture borders
=======================< cut >========================
Oh well.
