Ctrl-Alt-Fn has to be handled mostly by the kernel, because it works
on a machine where X is not even installed. When switching to a
console on which X is running, the kernel has to (somehow) inform
the X server that it's being reactivated, so that the X server can
arrange to get the screen redrawn; and the X server presumably has
to involve the window manager to install the correct colormap.
(It _is_ the window manager that manages colormaps, isn't it?)

Based on the OP's description, I suspect something in that chain
is failing. Since he said it worked OK with KDE, it seems that
this communication path works:

kernel --reactivate--> X server --restoreColormap--> KDE WM
    --installColormap--> X server --installColormap--> display driver

however it fails when KDE WM is replaced with FVWM. It may not be
an FVWM bug, but FVWM is somehow a factor.
