Its possible to pull the bits now (including a pre-build kernel for  
Fedora 11).

In thinking about this some more, the assorted options are currently:

1) run Fedora 11, download the kernel I built last night from Fedora  
build system:


2) git clone my lirc driver git tree, build a 2.6.31-rcX kernel (best  
to git clone linus' tree off git.kernel.org, then add me as a remote,  
I only have 5Mbps outbound).

3) grab just the lirc bits from git, using gitweb's snapshot  
capability, i.e.


Unpack them, then 'make -C /path/to/kernel/source M=$PWD  
modules' (assumes you have the config vars for lirc properly set, I  

If running on pre-2.6.31, you'll want to back out the 2.6.31-specific  
i2c changes, which this patch will do:


4) grab the lirc patches that are in my Fedora kernel build directly:


The second is only needed for pre-2.6.31.

All of the above also require some patching of the hdpvr driver as it  
exists in kernel 2.6.30, using this:


That's now a roll-up of things in Janne's hdpvr hg tree that aren't in  
the upstream kernel yet, and a few minor additional tweaks that I need  
to send over to Janne still.
