My only interest is in 2.6, and the messages appear to be from a
2.4 kernel.  It does seem that we are detecting a device incorrectly,
since we aren't finding an 8250-compatible serial port.

Unfortunately, we don't have tables of exclusion, nor do we have
a clean method to do that at present in any kernel.

What I'd like to see is the output from lspci -vvx from a range of
PCI cards with this problem to see if there is characteristic (eg,
the PCI class/programming interface IDs) we can pick up on.
