For those wanting to check their systems, this may help:
sed -ne '/^flags /{s/\b\(fpu\|tsc\|cx8\|cmov\)\b/%/g;s/[^%]*//g;s/%%%%/i686 SUPPORTED/p}' /proc/cpuinfo
which will output 'i686 SUPPORTED' only when those four flags are set
(assuming that '%' never normally appears in the flags line).
Cheers, Phil.
