OK I got it working manually;
Fist:

debian@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots
 0: PF----  -1 4D cape display variables
 1: PF----  -1
 2: PF----  -1
 3: PF----  -1

Than:

sudo sh -c "echo 'BB-UART2' > /sys/devices/platform/bone_capemgr/slots"

Again:

debian@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots
 0: PF----  -1 etc...
 1: PF----  -1
 2: PF----  -1
 3: PF----  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,BB-UART2

My testscript using UART2 now works. However, after a reboot all needs to
be done again. Not very satisfactory.
How can I get it installed on boot?
Please advise!
Regards,
Harke
