The BPP driver should work in very new 2.2 kernels, and there's parport
support in new 2.3 kernels (though I don't think the new 2.3 kernels work
on sparc32 yet)

Yes. The fix for the BPP driver is simple. Find the struct bpp_regs and
add __volatile__ to the declarations of all the variables in it.
