Well, as I said, you need to load if_harp:
kldload if_harp
AFTER loading if_hatm.
The you will see an hatm0 physical interface via 'atm show interface'. This
interface should behave exactly like other HARP interfaces. The comment
in NOTES is insofar correct as you cannot directly use hatm with HARP, but you
need the if_harp pseudo-driver between.

You may want to change HE_CONFIG_VPI_BITS and HE_CONFIG_VCI_BITS in
/usr/src/sys/dev/hatm/if_hatmconf.h (the sum must be 12 so you must change
both). Currently it is configured for 2 VPI bits. That gives you a maximum VPI
of 3.
