No, there isn't. I've been looking at fbterm's source code. The
"unprivileged" mode is actually a malfunction due to the user having
insufficient privilege to execute certain ioctl commands in the kernel
which configure the keyboard.
When fbterm executes as intended, all the "stolen" key combinations
(with the execption of C-<space> and C-M-k, which have, in effect, been
commented out in the key table) get remapped. This includes critical
Emacs key sequences such as C-M-e and C-M-c.
