Recall that a static variable lives in the global data along with the
other global variables: it doesn't get allocated on the stack.
I'm not familiar with the services you're using, but if I were going
to bet I would guess that notification callbacks -- especially those in
virtual drivers -- can't depend on their globals being available.

I believe Craig uses prc-tools 2.0. Unless one is using `-mown-gp',
this advice is long since out of date. CALLBACK_PROLOGUE-style tricks
are mostly unnecessary with 2.0.
