There have been some problems with vias re. cmov, e.g.:
 http://lists.debian.org/debian-glibc/2003/02/msg00005.html

You can check by doing

  $ cat /proc/cpuinfo
  processor : 0
  vendor_id : AuthenticAMD
  cpu family : 6
  model : 8
  model name : AMD Athlon(tm) XP 2200+
  stepping : 0
  cpu MHz : 1792.552
  cache size : 256 KB
  fdiv_bug : no
  hlt_bug : no
  f00f_bug : no
  coma_bug : no
  fpu : yes
  fpu_exception : yes
  cpuid level : 1
  wp : yes
  flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow ts
  bogomips : 3586.65
  clflush size : 32

and check the flags line.
