The keying in PCI slots indicates the supported voltage.
A 32 bit card that supports both 3.3V and 5.0V operation will have two edge
connector notches.
64 bit slots are frequently 3.3V only, while 32 bit slots almost always
support 5V cards.

66Mhz operation is only supported at 3.3V.

Yup, or the card wasn't fully inserted in the old slot.

The bottom line: this was a hardware problem, not a driver problem.
No new PCI ID needs to be added to the driver.
