[parisc-linux] 2.6 & pdc_console pb on c110: "Warning: unable to open an initial console."

[Ryan Bradetich]

Joel,

Even though you should not need the pdc_console for what you want to do,
pdc_console should work in theory.  It probably needs to be updated to
work with the 2.6 kernel.  I will add this to my TODO list.

Thanks,

- Ryan
