New driver required for EnE KB-3886 after XP SP2 install

I have a problem with my Medion 6100 laptop.
Since installing XP SP2, if I try to enter standby I get
the message that the EnE Keyboard KB-3886 driver is
preventing the system from entering standby.

The keyboard does not have a standby or hibernate button;
I enter standby by going through the Win Xp Start -
Shutdown - standby option on screen. Wake up is by
pushing the power button.

I have tried unsuccessfully to find an update for this
driver.

Would anyone know whether SP2 alters the original driver -
if so can I safely "roll back driver" and will this fix
work?

Or would it be that the original dirver is still
installed but does not work with SP2...in which case I
definitley need an updated driver....?
