[nSLUG] Hardware modem not detected by Ubuntu 5.04/ 2.6 kernel

I require help getting Unbuntu 5.04 to recognize my internal ISA
hardware modem.

The modem works fine with rh9 (2.4.2 kernel).

However, I've never had any success detecting the modem with any
distribution(MDK,RH,SuSe) using the 2.6 kernel including Ubuntu 5.04.

Details follow:

I have an:
        Internal CommCenter ISA modem
        with a Rockwell controller chip
        RCVDL 56ACF/SP
        R6761-21
        ROCKWELL 97
        9832 B62848-3
        MEXICO

Linmodems has confirmed it is a hardware modem(see quote):

        <<Your modem is a full hardware one....you have a full hardware
        one. It needs no special driver, which is why "RH9 detected it
        without a hitch">>
        
The modem is detected immediately with rh9 (2.4.2 kernel) and I've been
using rh9 and kppp to connect to the internet. RH9 uses ttyS2, irq5.
        

The excerpts from the /var/log/dmsg file for RH9 are as follows:
        .....
        Activating ISA DMA hang workarounds.
        isapnp: Scanning for PnP cards...
        isapnp: Card '56 Speakerphone srm'
        isapnp: 1 Plug & Play card detected total
        
and....
        
        Serial driver version 5.05c (2001-07-08) with MANY_PORTS
        MULTIPORT SHARE_IRQ SERIAL_PCI ISAPNP enabled
        ttyS0 at 0x03f8 (irq = 4) is a 16550A
        ttyS1 at 0x02f8 (irq = 3) is a 16550A
        ttyS2 at port 0x03e8 (irq = 4) is a 16550A
        
It's interesting to note that my BIOS printout puts the '56 Speakerphone
srm' on IRQ 5


Excerpts from the /var/log/dmsg file for (K)Unbuntu5.04 are as follows:

.....
        Activating ISA DMA hang workarounds.
        isapnp: Scanning for PnP cards...
        isapnp: Card '56 Speakerphone srm'
        isapnp: 1 Plug & Play card detected total

<<GOOD NEWS HERE - (K)UBUNTU DOES DETECT THE '56 Speakerphone srm'>>

and ....

        Serial: 8250/16550 driver $Revision: 1.90 $ 54 ports, IRQ
        sharing enabled
        ttyS0 at 0x03f8 (irq = 4) is a 16550A
        ttyS1 at 0x02f8 (irq = 3) is a 16550A
        ttyS0 at 0x03f8 (irq = 4) is a 16550A

Nothing mentioned about ttyS2, like in the RH9 dmsg file, and ttyS0 is
listed twice. 



I would like to switch/upgrade to Unbuntu 5.04/kernel 2.6.

Any suggestions on how to get Ubuntu 5.04 to detect my modem.
