As you did, "echo 7 >/proc/parport/0/irq". But since this won't make things
work early enough for PLIP what you probably need to do is use
"parport=0x378,7" on your kernel command line.

It's not a bug as such, just a slightly tricky feature. The problem is that
if we enable IRQs by default things go wrong for naive users who have
installed their soundcard on irq 7 as well and just want to use a printer.
By making them default to off it makes life slightly more awkward for PLIP
people but hopefully the failures are less mysterious and these users are
slightly more technically savvy anyway.
