Description Ivo Anjo 2008-02-05 00:17:47 UTC 
Version:            (using KDE 4.0.0)
Installed from:    SuSE RPMs
OS:                Linux

I didn't find "solid" to file this bug against, so I filed it under kdelibs.

Solid incorrectly identifies the capacities of my cpu. Here's the output from solid's tutorial3, that tests for cpu extensions:
tutorial3(29301) main: Intel MMX supported: true
tutorial3(29301) main: Intel SSE supported: false
tutorial3(29301) main: Intel SSE2 supported: false
tutorial3(29301) main: Intel SSE3 supported: false
tutorial3(29301) main: Intel SSE4 supported: false
tutorial3(29301) main: AMD 3DNOW supported: true
tutorial3(29301) main: PPC AltiVec supported: false

but my cpu (amd athlon xp) supports SSE (but not SSE >= 2), and /proc/cpuinfo confirms it:
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext3dnowext 3dnow up ts
