pport1 modules not working under RedHat

About a year ago I bought six powerline network devices since they were great option at that time and suited my home network requirement. Currently, I am on windows and would like to move all machines to linux but I am unable to use pport1 on Red hat 9.0, or Mandrake 9.0, or even Mandrake 8.0, or Turbolinux 7.3.
While, I was able to compile the pport1 source program successfully by changing the include directory to /usr/src/linux-2.4/include.
However when I run load_plx, I get the following errors for which I have no clue. I would very much appreciate your help on this for me to transition all my machines to Linux. If my RCA systemlink adapters does not work in Linux, I will have to unwillingly go back to the windows world :-(

Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

Here's the excerpt of output of 'dmesg' I ran after having above problems with
load_plx:
------------

I even tried running:
[root@neerajpc pport1-0.92]# /sbin/ifconfig parport0 10.127.84.105
SIOCSIFADDR: No such device
parport0: unknown interface: No such device
I was happyto use these devices with Suse 6.4 which all worked without problems, I am not sure but I think the kernel was 2.2.14.
