Thanks Paul 

Unfortuately removing all the drivers and doing 'make install' again,
didn't work. 

For the meantime, I have added the relevant modprobe -r and modprobe
lines into my /etc/conf.d/local.start file. This is a nice gentoo
facility that provides a workaround for problems like this

Hopefully before too long the driver I need will be in-kernel. 

cheers

Allan
