James,

I'm running kernel 2.6.33.7 on my Mandriva system.  Jarod was very kind 
and helped me get a working compilation of the zilog driver. I have 
lirc-0.8.7 and compiled the driver for that.  I'll be glad to tar up 
what worked for me and send it to you.  For what it's worth, I don't 
have an hd-pvr, but I do have two pvr-150's.

Regards,
R
