not to get to off topic and such.. but it feels slightly approriate
to say that linux 2.1.63 already has a bug fix for the pent F0 0F bug..
got this from a friend who's running a 2.1.x kernel..
checking for F00F bug ...<6>
Intel Pentium/[MMX] F0 0F bug detected - turning on
workaround.
moving IDT ... ... done
[root@dilithium /]# ./pentium_lockup
Illegal instruction (core dumped)
apparently it traps the op codes before they go on to the cpu..
