In order to make this work on my T43p, I set dev.acpi_ibm.0.events=1, so
that Fn-F4 generates an acpi_ibm event (which is handled by devd) rather
than a suspend event (which tells the kernel to suspend straightaway). I
have the block

notify 10 {
        match "system"          "ACPI";
        match "subsystem"       "IBM";
        match "notify"          "0x04";
        action "/usr/sbin/zzz";
};

in my devd.conf, so that it calls zzz, which does the right thing.
