I don't believe this is the correct approach. You don't want to be modifying the server and you can't arbitrarily add a new KEYEVENTF_* value. You can't assume that applications won't leave junk in the non-standard bits of the flags when they call SendInput() or keybd_event().
This needs to be implemented entirely within the X11 driver. It needs to properly translate your X11 keyboard layout into Win32 behavior. If the problem is that AltGr is mapping to VK_MENU, and thus causing key events to generate WM_SYSKEYDOWN/UP and not go through translation, then you need to make AltGr not map to VK_MENU. Although you really need to test that on Windows. My understanding is that AltGr appears to Windows apps as Alt+Control.
In any case, I know that, on Mac OS X, the Option key is used similarly to AltGr. It accesses additional characters from the keyboard layout. This works when Option is configured in the X keymap to generate XK_Mode_switch. It requires no changes to Wine. So perhaps the right approach is to make XK_ISO_Level3_Shift and XK_ISO_Group_Shift behave the same way as XK_Mode_switch. (You could also just change your X keymap to actually map the key to XK_Mode_switch.)

Oh, and I forgot to mention: please don't rename variables unnecessarily (AltGrMask -> KeyEventModifiers), make whitespace changes on lines you're not otherwise modifying (stuff in X11DRV_InitKeyboard()), or change trace formats arbitrarily (%x -> %X).
