SIS DRI and libGL warning: 3D driver claims to not support visual 0x4a

Hello Xorg users and developers. I have a problem with the SIS DRI
driver. I'm using Ubuntu Feisty-current with SIS630 DRI-enabled
graphics. Whenever I start a 3D-accelerated application I get a
warning:
libGL warning: 3D driver claims to not support visual 0x4a
I wouldn't be worried if most if not all 3D applications fail to
display properly. Of all the 3D games I've tried only Neverball works
without visual glitches. The rest either fail to display graphics
correctly or crash altogether. Those were just tests though.
What I really wanted to run was AIGLX with Beryl. AIGLX works fine,
Composite is enabled. However, Beryl fails to start:
tom at srebrny:~$ beryl-manager

libGL warning: 3D driver claims to not support visual 0x4a
Root visual is not a double buffered GL visual
libGL warning: 3D driver claims to not support visual 0x4a
beryl: Root visual is not a double buffered GL visual
beryl: Failed to manage screen: 0
beryl: No manageable screens found on display :0.0
Now, I'm no expert at this, but the SIS DRI is badly missing
GL_ARB_texture_non_power_of_two instruction and the "double buffered
GL visual", whatever that means.
Here's my glxinfo:

I would honestly appreciate any input on this. I know, I know SiS630
is old and everyone forgot about it already. Some of us can't afford
the fancy cards to have the desktop effects enabled. Besides this is a
laptop, can't really change anything here. So I guess there should be
some work done that I would have done myself (I'm a translator for
GNOME and other projects and I do a lot of non-dev work for OSS), but
alas, lack the programming skills. Thus I ask here, is someone able to
fix the SIS DRI driver?
With regards,
Tomasz Dominikowski
