    Not to keep complaining, but I now have the following issue. I running
    Fedora Cores 2.6.15-1.1826 kernel. When I run dmesg I now see this:

    Serial: 8250/16550 driver $Revision: 1.90 $ 2 ports, IRQ sharing enabled
    serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
    00:06: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

    before 2.6.15 I saw
    Serial: 8250/16550 driver $Revision: 1.90 $ 32 ports, IRQ sharing enabled

    The serial driver now correctly reports that I have two serial ports instead
    of 32. So shouldn't the patch register the minimum of
    CONFIG_SERIAL_8250_NR_UARTS and the number of serial ports detected by the
    serial driver?
