So how quick one can throw something together to test this depends on  
several factors. If you're running Fedora 11, there's a binary kernel  
package sitting in the Fedora build system that has all the necessary  
bits included. If you're running an upstream-ish 2.6.31-rc kernel, the  
bits in my git tree will build and *hopefully* work, but I've not  
actually tested them there. I did most of my debugging and testing on  
a 2.6.30 kernel, which is built using the lirc bits from my git tree,  
with the 2.6.31-specific i2c changes backed out. Oh, and this also  
requires some minor patching of the hdpvr driver, regardless of kernel  
version at the moment.

Long story short, Fedora users can simply install the kernel here:

http://kojipkgs.fedoraproject.org/packages/kernel/2.6.30.5/45.fc11/

Then slap the firmware image and lircd.conf from blushingpenguin in / 
lib/firmware and /etc respectively, and go to town.

Other distros, particularly those with kernels earlier than 2.6.30...  
Well, you've got some work ahead of you, since I don't know what form  
of hdpvr driver or lirc drivers are already present... For 2.6.30, the  
three patches here are what are included in the Fedora kernel build I  
did:
