Strange, the code in __intel_proc_init_ftzdaz looks like the right code. Right now I can not say from what extention "stmxcsr" come from. Here is the features from dmesg: Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,C MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
Google seems to indicate it's an SSE instruction.
