sorry . . . don't work for me.  Here is the applicable section of my 
rc.modules file.  notice that I also changed the parallel port support 
section to reflect the same file name difference in the 2.6.7 kernel.

if there is a typo, I haven't been able to see it.  ergo, I have cut and 
pasted it directly from the file.  if I send print jobs to the printer, I 
get no output, then when I modprobe lp and or parport_pc, all jobs in the 
queue begin to print.

tis perplexing.  I can live with the modprobe calls in rc.local, I guess it 
is just not elegant.
