Building kernel : CPUID_FXSR undeclared (first use...)

Hi,

I've just installed a 8-BETA1 on my new computer, checkouted the
sources via svn (http://svn.freebsd.org/base/head).

I've recompiled a kernel without debug and whitheness sucessfully, but
when i've try to remove some things and it fails.

The kernel configuration is here : http://banane.rhaamo.li/NAWAK

The CPU is :

  CPU: Intel(R) Core(TM)2 Quad  CPU   Q9300  _at_ 2.50GHz (2499.73-MHz
K8-class CPU)
  Origin = "GenuineIntel"  Id = 0x10677  Stepping = 7
  Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,
HTT,TM,PBE>
  Features2=0x8e3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1>
  AMD Features=0x20000800<SYSCALL,LM>
  AMD Features2=0x1<LAHF>
  TSC: P-state invariant

The kernel build error:

I've also experiencing the same issue with audio/oss, it failed on
CPUID_FXSR, but now fail with CPU_SSE or CPU_SSE2...

If someone have an idea with this problem,

Thanks.
