I think that is part of the problem: Even though you hold down CTRL and
ALT before you press F1, you still get the normal "F1" keysymbol and not
the "XF86_Switch_VT_1" one. If I run "xev" and press the three keys then
I never see the KeyPress event for F1 because X switches to the
terminal. If, on the other hand, I disable VT switching in my xorg.conf
then I still do not get any event for F1 if I press it while CTRL + ALT
are held down. Something within X obviously intercepts these events and
processes them or deletes them from the event queue, depending on the
settings in xorg.conf.

I have the same here.

Check what is assigned to keycode 67. I see this:
$ xmodmap -pk | egrep '^[ ]+67 '
67 0xffbe (F1) 0x1008fe01 (XF86_Switch_VT_1)
If your output looks different then you can try if
xmodmap -e 'keycode 67 = F1 XF86_Switch_VT_1'
restores the VT switching.
