There had been changes regarding parport between these kernels, and
you'd better use a newer umax_pp backend

What are the parport informations as shown by 'dmesg', for instance,
on my PC it is:
parport0: PC-style at 0x378 (0x778), irq 7, dma 3
Also, if the parport support is built as a module, make sure that
you only pass the io arg, irq and dma should be set to auto. It is the
way it works the best. I use (in /etc/modules.conf):
options parport_pc io=0x378 irq=auto dma=auto
