I have a couple SMC Power155 PCI ATM cards, which are apparently just
OEM versions of the Efficient card.  I played with them a few years ago
and I believe they probed just fine, though I never actually used them.

Now, however, something isn't working.

en0 at pci0 dev 11 function 0: Efficent Networks 155P-MF1 ATM (ASIC) (rev. 0x00)
en0: interrupting at irq 10

Any ideas?
