Not sure if I've tried a 32-bit kernel, but I don't know of any reason why 32-bit vs. 64-bit should matter... The trace seems vaguely familiar, but its been a while. I don't recall seeing an i2c_master_send failing with a -5 (-EIO) though.
The driver is littered with a few places where we check for errors from i2c_master_send(), would need to know which call site it is that's failing. From the sequence there, its gotta be either the one in send_data_block() or one of the ones in send_boot_data(). If you can figure out which one is failing, that might shed some light on the matter.
Also, what incarnation of lirc_zilog.c are you using? Could be there's a fix missing that's in the git tree, or a regression added to the git tree, depending on which one you're using... :) I really need to dust off my own hdpvr and poke at it some, I think...
