Flash-Player _requires_ SSE2 support since version 11.
But certain older 32bit CPUs (in particular AMD Athlons and Semprons) do not
have that.

"Ung�ltiger Maschinenbefehl" would indicate that this is indeed your problem.

"cat /proc/cpuinfo" will show you whether your CPU has SSE2 support or not (the
"flags" line should include "sse2" if it is supported).

If your CPU does not support it, there's no way to get a current Flash-Player
to work, your only option would be to install the ancient version 10 (e.g.
download and install the package included in openSUSE 11.4).
And since Flash-Player is closed-source, there's nothing openSUSE can do about
that.
