I didn't have any trouble binding these (as long as you force convert-meta
to off), but now I don't think that's what you're talking about.

Bash-4.2/readline-6.2 has a non-settable timeout that allows readline to
distinguish between an ESC as a command to switch to vi command mode and
an ESC-prefixed key sequence. The development versions make it a user-
settable variable (keyseq-timeout).
The following inputrc lets me use ESC-TAB for completion and TAB as TAB
using the development version of bash:
set convert-meta on
set keymap vi-insert
META-TAB:complete
TAB:self-insert
It will probably work with bash-4.2 if you can configure your terminal
emulator to convert meta keys to an escape-prefixed key sequence. (The
Terminal application on Mac OS X lets me use the option key this way,
and it works there.)
