[linux-dvb] GPF on 64-Bit

I have a Hauppauge DVB-s Nova CI that I have just put into my new Xeon 
em64t server (Gentoo 2.6.14-r1) and am getting a GPF. I have been using 
this card on my P4 2.8 for several months without a problem. Both 
kernels are SMP to support hyperthreading but the Xeon is 64-bit. I saw 
that someone else had a similar problem on an amd64 
This is what I get in dmesg:
tda1004x: found firmware revision 0 -- invalid
tda1004x: waiting for firmware upload (dvb-fe-tda10045.fw)...
tda1004x: firmware upload complete
tda1004x: found firmware revision 2c -- ok
dvb_ca adapter 0: DVB CAM detected and initialised successfully
general protection fault: 0000 [1] SMP
