RE: [Ltib] EA3250 problem with console display driver (PCIMEM_BASE)

Hi Miguel,

I've never tried using this driver before, but  I agree with
Alan's assessment that you'll probably need to modify more than
just the PCIMEM_BASE macro to make it work.

You should be able to get cosnole output on the display using
the framebuffer console. Will that work?
