I've been able to install mesa from experimental (packages: libdrm-intel1, libdrm2, libgl1-mesa-dev, libgl1-mesa-dri, libgl1-mesa-glx, mesa-common-dev) in a Lenny live cd environment. The bug still shows on my system. It seems that the issue is indeed specific to this graphics card model.
If you want me to test something, please let me know. Otherwise, don't worry too much. There aren't probably many such cards still being used. Myself, I can work around the bug in my programs by replacing GL_LINE_LOOPs with GL_LINE_STRIPs and repeating the start/end point (the extra point shouldn't affect performance very much). And I've been thinking of buying a new card already for some time, maybe this will make me resolve myself eventually.
