For any slot card that Autoconfig cannot find a module in the kernel with a
matching board and version number, Autoconfig prints a warning message to the
system console.
For example, if autoconfig cannot find the driver for an Ethernet card you
have installed, it prints a message similar to the following:
Warning cannot find driver(s) for device ID 5 Version 7.0
It is just an informational warning and does not signify any real error.
If the card is a monitor card, then the error is irrelevant, since the card
will work with the default monitor kernel driver.
