This may or may not be helpful; however in my case, on an Ultra 60,
CONFIG_PARPORT_PC_FIFO causes printing to not work. Compiling this
option out makes it work.
It's a shame, really -- outside of this flaw, the shipped kernel works
flawlessly (and for myself, I would have enjoyed the feature of not
having to recompile on kernel updates).
