Quick answer: lots of them.
Quick caveat: they have to be ARCnet cards.
Almost all ARCnet cards are based on either the old SMC COM9026 chip or chips that are compatible with it. This is pretty convenient, because it means the same ARCnet driver will work with all of them. We call these cards COM90xx cards because of the numbers their chipsets tend to have.
There are some exceptions, though:
Cards using the COM20020 chip aren't quite compatible -- they need a special initialization sequence, mostly, but once they're initialized they have a few extra features we can use if we treat them specially. ISA cards using this chip use the COM20020 driver.
Some cards are based on the COM90xx chip, but don't use the normal memory mapping modes. For these, we have the com90io driver. Most newer COM90xx cards will work with the com90io driver even if they work with the com90xx driver, but the com90xx driver is slightly faster.
And of course, some cards are exactly the opposite: they memory-map everything instead of I/O-mapping it. These cards were commonly found on Amigas, which didn't have I/O ports at all. For these, we have the RIM I driver.
