Ok. This is indeed still a 915 GPU, the laptop variant

[...]
#define INTEL_I915GM_IDS(info)                          \
        INTEL_VGA_DEVICE(0x2592, info) /* I915_GM */

I'm afraid you need to live with nomodeset, i.e. fbdev unaccelerated graphics
driver. Neither upstream nor SUSE is going to investigate issues
on an about 15 years old 32bit system, but things may get fixed again upstream
by accident. ;-)
