from http://www.ccrc.wustl.edu/pub/chuck/tech/bsdatm/bsdatm.html, it seems
like the drivers should be include as port of NetBSD, OpenBSD, and
FreeBSD or atleast they say it supports those cards:

CONFIGURATION 

To configure BSD ATM into a kernel, add one of the following lines to the
kernel's config file: 

  en*     at sbus? slot ? offset ?        # NetBSD SBUS
  en*     at pci? dev ? function ?        # NetBSD, OpenBSD PCI
  device en0                              # FreeBSD PCI

To configure NATM into a kernel, add the following like to the kernel's
config file: 

  options NATM

If all goes well the kernel should print something like this during
autoconfig: 

On NetBSD or OpenBSD with a PCI device: 

  en0 at pci0 dev 14 function 0
  en0: interrupting at irq 3
  en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board
RAM
  en0: maximum DMA burst length = 64 bytes
  en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated

NetBSD with an SBUS device: 

  en0 at sbus0 slot 2 offset 0x0
  en0: claims to be at the following IPLs: 16 1 2 3 5 7 9 13 
  en0: we choose IPL 5
  en0: midway v0, board IDs 0.2, SUNI, 512KB on-board RAM
  en0: maximum DMA burst length = 4 bytes
  en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated

FreeBSD with a PCI device: 

  en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16
  en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board
RAM
  en0: maximum DMA burst length = 64 bytes
  en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated
