Is there any issue with emulating MMX?
Yes. MMX is not currently emulated.
If there's a command line option to disable the use of MMX you can try
it, otherwise wait for it to be implemented (or implement it
yourself). I'll try to do it for 2.6.37, but can't promise anything.
You can also run qemu with -cpu qemu32,-mmx. That will expose a cpu
without mmx support; hopefully the guest kernel will see that and avoid
mmx instructions.
