pentium IV single processor, gcc (GCC) 4.0.3 20060128

During boot, I normally get:
parport0: irq 7 detected
lp0: using parport0 (polling).

Instead, I got this, written by hand:
parport0:irq 7 detected

This oops is simplified. I can get the exact text if
that really matters.  It is much more to write down and
I don't usually have my camera at work.
