Well, it's almost always going to take *some* amount of time to switch
VT's.  I've only seen something approaching lightning-fast VT switches
on machines using fbcon and with video modes matched between the X
server and virtual console.

Okay.  See below.

I see you're repeating as "imps2".  The following item was recently
added to the xfree86 package NEWS.Debian file, and will appear in the
next release.  Can you please try out its advice?

  * GPM users only: those who use the the GPM repeater as the XFree86 X
    server's mouse device should note that the mouse driver in XFree86 4.3.0
    has been rewritten in such a way that using any protocol other than
    "IntelliMouse" on the XFree86 side and "ms3" on the GPM side does not work
    well.  If you have configured GPM as a repeater, are using it with the
    XFree86 X server, and are using anything other than "ms3" as the repeating
    protocol, you will likely want to change it to "ms3".  If your
    XF86Config-4 file is automatically handled (see the news entry for xfree86
    4.2.1-11) and uses /dev/gpmdata as the port for the configured mouse, the
    protocol will automatically be migrated to "IntelliMouse" if necessary.
    Otherwise, you will likely want to edit the /etc/X11/XF86Config-4 file
    after installing this package to change any configured input devices using
    the "mouse" driver and "/dev/gpmdata" as the "Device" option to set the
    "Protocol" option to "IntelliMouse".

If you go back to using /dev/gpmdata for your XFree86 input device, but
have GPM repeat as "ms3" instead of "imps2", does the situation improve?
