 Kernel panic - not syncing: Attempted to kill init!

The box has no HiSax card installed.

the reason for the crash is add_timer() done on an already running
timer. This happens because for some reason CARD_INIT is called twice.

this patch works this problem around by using mod_timer() - this gets
a booting system - but it would be nice to figure out why CARD_INIT
is done twice.
