Maybe try specifying the IRQ manually, per https://www.kernel.org/doc/Documentation/parport.txt ? I haven't used a real parallel port under Linux since 2.2, so beyond that, no idea.
Yup, that's like the only useful doc on the net, and I tried everything in there. The IRQ that is autoassigned is correct, and the port works, it's the lack of DMA that seems to be killing me.
I guess I'm the lucky owner of a buggy board (Intel!!!) or kernel... or both, as far as parport is concerned.
