I have a weird situation. On my desktop (intel board and X4500 graphics) the original Tuxkart works fine, but ExtremeTuxracer and Supertuxkart are jerky. Curiously, on my laptop (dell Mini 9 with intel 950 graphics) the opposite is true: STuxkart and Etracer work great, but the original Tuxkart is very jerky. If I understand correctly, Tuxkart does not require mesa while the other two do; that's why the question title.
Before we get into hardware issues, on either Ubuntu or Gentoo all three games work great on both systems. In all cases, the output of glinfo and xdpyinfo are the same, modulo version. In Ubuntu 10.4, the version is older. In Ubuntu 10.10, the version is newer. In Gentoo, versions are about the same. I have tried running exactly the same kernel (built on arch) to drive the ubuntu/gentoo setups and the games all work fine, so that takes the kernel out of the picture. All use the same kernel driver.
Anybody have any idea where I'm fouled up on this?
Thanks,

Answering my own post a little, but maybe someone else can add to this. On the desktop, something about mesa is certainly most of the issue. If I pull libGL.so.1.2 from Ubuntu and just plug in in directly, most things behave properly.
Not true on the atom/laptop, so there's a different issue to uncover.
I thought it would be best to build the mesa package from abs and then try messing with the configure options. However, when I try to build it with a pristine PKGBUILD I get a failure:
python util/u_format_table.py util/u_format.csv > util/u_format_table.c
File "indices/u_indices_gen.py", line 63
print '''/* File automatically generated by indices.py */'''

SyntaxError: invalid syntax

Please post this PKGBUILD. Mesa must be patched against python2.

Here's the one I used (straight from ABS):

You're probably on the right track, since when I ran makepkg -s it pulled in python (3). Thanks!

You can use Mesa 7.9 from testing. It's already patched.

I might give that a shot, but I think it would mean replacing a lot of other packages also...? As it is, I found that if I change makedepends to from python to python2 and then make a symlink /usr/bin/python -> /usr/bin/python2.7 it builds.
That being the case, I think I'll try changing some params on the current version rather than jumping ahead -- might give me a better chance to isolate the issue (change as little as you can during incremental testing. My usual technique, anyway).
Thanks again!

You can easily apply patch (sed) to 7.8.2

Patching it got me building, but I didn't find a fix before mesa 7.9 was released from testing. The good news is, 7.9 mostly got things working. The bad news, not entirely. Instead of constant jerking, now I have an occasional flash or jerk. This is an improvement but something is still a bit wonky.
I'll continue fussing with it, but now I'll be working with 7.9 instead.
Thanks again!
ps: in the event anyone has been curious, the problem with tuxkart is a bit more complicated -- I've been able to duplicate it on several systems now. But as far as I can tell, it's not a mesa issue. So the original description is of two pretty much unrelated problems. I'm only going to address the mesa issues here (and have little hope for a resolution on such old software as the original tuxkart. I know I'm on my own there!)
