Correct. Anything gossamer based, B&W G3, PCI G4 and Mainstreet,
Wallstreet, PDQ. I'm not sure on the pismo and lombard, but I assume they
are bmac too, but like the B&W G3 and PCI G4's they support 100MB/sec.

The Broadcom BCM57xx was added in with Sawtooth and later.

The nice thing about Windows is - It does not just crash, it displays a
dialog box and lets you press 'OK' first.
