Though truth be told, half the issue w/the i2c and imon users is simply
documentation. lirc_i2c changed in the 2.6.33 era due to i2c subsystem
changes, and its not been possible to bind it to pvr-150 cards with a
zilog z8 IR chip since then, but lirc_zilog binds just fine. I've had at
least one person on irc confirm that simply editing
/etc/lirc/hardware.conf, swapping lirc_i2c for lirc_zilog, got them back
to fully functional. The imon case, tools are apparently still telling
imon users they need to use lirc_imon and configuring things to talk to a
/dev/lircX device node that doesn't get created, as their imon devices are
now handled by the imon driver. Its a pure scancode-based device, so the
ir-core lirc bridge driver is never invoked, as there's no raw IR to pass
-- lirc_imon was hackily passing scancodes via its lirc device interface
rather than raw IR.

But some of the imon devices w/the current Ubuntu kernel don't get set up
correctly (one specific 0xffdc model, anyway), and there's definitely an
issue present with key releases not happening as they should in certain
cases -- see https://bugzilla.kernel.org/show_bug.cgi?id=16351 .

And while you're at it, fancy adding a patch to improves the Linux HID
layer to the point where the TiVo Slide remotes Just Work(tm) right out of
the box too? :)

https://patchwork.kernel.org/patch/161481/

I've been contacted by more than a few Ubuntu users anxious to use these
remotes with both MythTV and XBMC.
