You can try to force the parport irq via procfs.
echo 7 >/proc/parport/?/irq
but be sure to apply my patch (I will sent it to you via private email) that fix a bug in parport_procfs before. Be sure also to not run "echo 0>/proc/parport/?/irq" because the parport procfs will free the 0 irq in order to gain it and your machine will hang (of course if int 0 is the timer interrupt as with i386).
