being curious, did you compare the battery level before and after ?

I've no idea on how the modem is working too but at least I can see that
there's a irq handler for a "modem wakeup" interrupt. Unfortunately, I
don't see where the gpio is configured to do interrupts.

Can you try adding :
s3c2410_gpio_cfgpin(GTA01_IRQ_MODEM, S3C2410_GPF1_EINT1);

before set_irq_type(GTA01_IRQ_MODEM, IRQT_RISING); in
mach-gta01:gta01_machine_init() ?
