Afraid not.  Using a manual version of this (suspending from a vt,
issuing the post and switching back to X) causes the X server to crash
as soon as it is switched to.

Just to try a more cautious test, suspending with X not running, then
resuming, then doing vbetool post then starting X also crashes.  

Curiously enough, If I just start X and no clients at all, it comes up
with the X cursor and I can move the mouse.  As soon as I connect a
client like an Xterm, it crashes.
