You can always find out what cpu flags you support by running "cat
/proc/cpuinfo" and looking at the "flags:" line

Here's mine as an example:
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow

So I'd set the mmx and 3dnow flags but not sse or sse2.
