Apparently, your config. is ok. I made some test with ATM at the end of
November (look at the Mail archive for the configuration and result).
What i found, is that the Fore ATM card (PCA200E not LE) fail to run
MPLS. You can establish connection but can't send any data : the kernel
crash. I change for ENI ATM card and it work well.

I'll test the new 0.990 version in the next days and report my result
ASAP.

To have a full ping working, you need to establish a full
bi-directionnal label ie. one for each direction, but, be carrefull, you
have to choose two differents VPI/VCI : this a limitation due to the ATM
driver. You can establish a bi-directionnal connection, Input only or
Output only connection. But, when you choose Input or Output only
connection, the remaining direction become unavailable :-(
