File a package request or something along those lines, I suppose. Not
much that can be done about that on the lirc list. ;)

Someone else I talked to said they actually found a Debian v4l-utils
0.8.1 package with ir-keytable in it.

Same person who found that v4l-utils package reported this as well.
The code in the Ubuntu kernel is a bit dated, and I've already tried
talking to Canonical kernel folk about updating assorted ir-core code
in their kernel, but they rejected the idea (doesn't meet the Ubuntu
"Stable Release Update" guidelines), but they may provide a separate
package with (dkms?) modules in it at some point. Alternatively,
there's a 2.6.36 kernel build for Ubuntu available somewhere, and
(same person again) told me that ir-keytable works just fine with the
imon driver in that kernel.
