it's getting stranger and stranger

now that I have included my workaround in /etc/acpi/sleepbtn.sh I can find
the following different entries in the acpi logfile:

this is the first suspend using Fn+F4

but the second time not a ibm/hotkey HKEY 00000080 00001004 event is
reported and handeled but a button/sleep SLPB 00000080 00000001
resulting in this log entry:
