RFR (S) 8023956 [2nd post]: Provide a work-around to broken Linux 32 bit "Exec Shield" using CS for NX emulation (crashing with SI_KERNEL)

[David Simms]

Cheers,

I think keep the SI_KERNEL message, it is still correct. Could be other 
issues now or in the future, where the Linux kernel has killed us due 
the an unknown trap. It requires some extra attention to the Linux 
distro when encountering such issues (good hint for support issues).
