Um. What? "HD-PVR 150" does not add up. The Hauppauge WinTV PVR-150
and Hauppauge HD-PVR are two different products, I presume you're
actually referring to the latter.

It does work, but that remote, imo, is trash.

The "LIRC program" doesn't need to be patched at all. You need an
hdpvr driver that has the i2c-connected IR part enabled, and an lirc
kernel driver (lirc_zilog) to talk to it. The lirc userspace remains
unchanged.

No clue what the LIRC_DEVICES="hauppauge" part actually does, or why
your distro is apparently still providing a pre1 snapshot, given that
pre2, pre3 and final have all since shipped too... But at least the
version issue should be neither here nor there in this case.

Is there a more recent version of this package that I can download from somewhere?

The lirc_zilog kernel driver is provided directly in kernel 2.6.36.
The above referenced tree is a fair bit outdated now. Though, there
hasn't been much churn in lirc_zilog.c of late, so that may not be
relevant. Of course, I should also note that lirc 0.8.7 probably won't
work right away with the in-kernel lirc bits, as the ioctl interface
has changed, and the lirc maintainer is slacking on putting out a
0.9.0-pre1 release with the necessary ioctl changes incorporated...
Hm, maybe I should get that done tomorrow.
