I confirm that it somewhat works with debug enabled. Configuration:
604e/233, 70ns RAM, CV64/3D with 1280x1024-8, XFree 4.0.2 running.
Somwhat means that the data is not entirely correct when arriving at the
printer (I have a PostScript printer). Therefore I get strange results, but 
most of it is still readable.

If I replace the printk with mb() it does not work at all.

It seems to be partially a tming problem, but not entirely. As I said, I once
inserted delay loops that would only allow to write about 1 Bps to the CIA, but
that did not help. There must be more to the dprintk call.

BTW, I have not been on IRC for some time, is some of you around there
sometimes?
