That didn't help either. dmesg now reports

parport0: PC-style at 0x3bc [SPP]

which is the standard lp0 address, but I get the same "Operation not
supported" message when I try to cat to /dev/lp0.

The following is a Python RSA implementation. According to the US Government
these three lines are "munitions" and posting them makes me an international
arms trafficker! Join me in civil disobedience; add these lines of code to
your .sig block to help get this stupid and unconstitutional law changed.
============================================================================
from sys import*;from string import*;a=argv;[s,p,q]=filter(lambda x:x[:1]!=
'-',a);d='-d'in a;e,n=atol(p,16),atol(q,16);l=(len(q)+1)/2;o,inb=l-d,l-1+d
while s:s=stdin.read(inb);s and map(stdout.write,map(lambda i,b=pow(reduce(
lambda x,y:(x<<8L)+y,map(ord,s)),e,n):chr(b>>8*i&255),range(o-1,-1,-1)))

Everything you know is wrong. But some of it is a useful first approximation.
