Description of problem:
We installed a Lava dual serial port card in a HP xw6200 system

The two serial ports are setup by kudzu to be modems even though
there is nothing connected to them. 

lspci output:

02:09.0 Serial controller: Lava Computer mfg Inc: Unknown device 0110 (prog-if 02 [16550])
        Flags: slow devsel, IRQ 5
        I/O ports at 3400 [size=8]

02:09.1 Serial controller: Lava Computer mfg Inc: Unknown device 0111 (prog-if 02 [16550])
        Flags: slow devsel, IRQ 5
        I/O ports at 3408 [size=8]



Version-Release number of selected component (if applicable):
kudzu-1.1.22.9-1

How reproducible:
Always

Steps to Reproduce:
1. Install a Lava dual serial port
2. Reboot
3.
  

Actual Results:  ll /dev/modem*
lrwxrwxrwx    1 root     root  10 Jul  1 10:41 /dev/modem -> /dev/ttyS4
lrwxr-xr-x    1 root     root  10 Jul  1 10:41 /dev/modem1 -> /dev/ttyS5

Relevant portion of /etc/sysconfig/hwconf:
class: MODEM
bus: PCI
detached: 0
device: ttyS4
driver: unknown
desc: "Lava Computer mfg Inc|0110"
vendorId: 1407
deviceId: 0110
subVendorId: 0000
subDeviceId: 0000
pciType: 1
pcibus:  2
pcidev:  9
pcifn:  0
-
class: MODEM
bus: PCI
detached: 0
device: ttyS5
driver: unknown
desc: "Lava Computer mfg Inc|0111"
vendorId: 1407
deviceId: 0111
subVendorId: 0000
subDeviceId: 0000
pciType: 1
pcibus:  2
pcidev:  9
pcifn:  1


Expected Results:  kudzu shouldn't identify them as modems.

With PCI serial ports, there's not a good way to distinguish a PCI modem that
shows up as a serial port, as opposed to a raw PCI serial port that you might
attach a modem to.

At this point, this code is not going to change for RHEL 3 or RHEL 4, and
probably won't change appreciably for future releases.
