A quick look in /proc/interrupts, showed that 3c589_cs was using IRQ3. 
Uncommenting the line:
exclude irq 3
in /etc/pcmcia/config.opts
And restarting pcmcia and network fixed it.

Thanks for all the replies anyway ...

Now to see if I can
1)Convice Mandrake to get the Mandrake tools to do this
2)Package the rest of the required software and get it into cooker/contrib

On that note, what is the status of the thinkpad kernel modules? Should 
I be requesting the kernel maintainer to build them in the stock kernel? 
Are they going to be submitted to lkml any time soon?

Regards,
Buchan
