Realtek 8101e

Can anybody help me with this?
After much faffing around I managed to get a driver for this network card
from realtek that compiled.
I've unzipped and un cpio'd the initrd from the imaging ISO CD.
I've copied the compiled r8101.ko into
/lib/modules/2.6.16.46-override-default/initrd.
I've the re cpio'd the files and re gzipped them as per documentation.
No joy - the imaging CD behaves like the ko isnt there pressing alt-f4
when booting the machine from the cd reveals it is unsucessfully tring to
use the r6189 driver. I've tried editing the module.config and modules.dep
files, I've even tried addind a insmod="r8101.ko" to linuxrc.config to no
avail (the kernel panics)
What am I missing? What step is it I have missed that tells the o/s on the
imaging ISO about the r8101.ko?
I'm using zen 7.1 sp1 ir1 hp1 (ie the latest thing from novell, there's no
upgrade I can try).

Help please?
