Well, earlyprintk will not work, as you need PCI up and running. And I have some code that barely works for this already, perhaps Eric and I should work together on this :) > So we need one client program on host side.

I'll knock up a "real" driver for the device later today and send it to Linus, as it's trivial to do so, and will make it simpler than using the module parameters. thanks, greg k-h -- linuxbios mailing list linuxbios@linuxbios.org http://www.openbios.org/mailman/listinfo/linuxbios
