For some value of, yes. All the hdpvr driver bits are in Janne's hdpvr  
tree, but I don't believe they've been pulled over to the main v4l-dvb  
tree, and definitely didn't go into kernel 2.6.31. The lirc bits are  
in my lirc git tree. I suppose I should forward a copy of things over  
to Mark Weaver, the originator of lirc_pvr150, but at this point, its  
quite different from lirc_zilog, I believe (2.6.31 i2c changes, hdpvr  
support additions, other cleanups)...
