Sorry Beto, I must have been dreaming :)  I have that too, but did try
'sysctl dev.acpi_lid.0.wake=0'.  With that, no keys at all but only
pressing the power button (not for too long!) will wake it up (phew).

Anyway, after a reboot - having noticed that since my verbose boot the
other day, each ACPI suspend/resume is VERY chatty in messages - it's
still working the same.  So eat this message ..
