Hey! Thanks for the response!

That did the trick.  I now have built modules.  I'm running Mythbuntu
9.10 (kernel 2.6.31.)

I ran these two commands to install the modules that (I think) had
changes in them...
insmod lirc_dev.ko
insmod lirc_zilog.ko

I saw no errors.  I can see lirc_zilog in lsmod and dmesg said
"lirc_dev: IR Remote Control driver registered, major 251"

Sadly I'm away from home and the HD-PVR is powered off so I can't test
much further than this.  If everything is working I should see a new
lirc entry in /dev, correct?
