pxafb as module...

I tried again to compile pxafb as module...
After insmodding it I get:

insmod cfbcopyarea.ko

The same error appear both with myself compiled zImage+Initrd and with
Michael h2200 modular zImage+Initrd.

pxafb is insmodded in a permanent way, since it hasn't an __exit
function.

Any idea to solve this issue?

Ciao, Eddi
