Actually, I'm just going to mark this as a duplicate of bug 296500 so
that everyone is automatically notified when the kernel with this patch
has been moved to the intrepid-proposed repository for testing.
Luiz, thanks for the usptream reference. The patch you mention was
recently applied to the Intrepid kernel when it pulled in the upstream
2.6.27.5 patch set - see Bug 296500:

Thanks for the tip on sudo. I have been investigating and there is yet another
way for setting those parameters using the sysctl command. And it looks like
the correct/best way of perpetuating the settings is through the
/etc/sysctl.conf file, that loads sysctl values at boot time. See

hardware in your machine (e.g. wifi card).
