Re: zaurus turns off when picogui running

the error seems to be  the timer_vidblank part.
when just commenting out

  if (timer_vidblank && timer_eval(timer_vidblank + timer_lastactivity))
    drivermessage(PGDM_POWER,PG_POWER_VIDBLANK,NULL);

the error does not appear.
i added some printf statements before these lines with

  printf("timer_vidblank: %d\n\r",timer_vidblank);
  printf("eval statement: %d\n\r",timer_eval(timer_vidblank + 
timer_lastactivity));

the output right after starting pgserver on the zaurus is

# pgserver
timer_vidblank: 600
eval statement: 0
timer_vidblank: 600
eval statement: 1

all this in < 3 secs (so oviously not 60 as configured). so it seems the 
timer_eval function behaves somehow different.
i wasn`t able to track this down further. hope that helps somehow !?

bye,peter
