I think you're right. I can almost fully bring back this VAIO (except 
for the network and wireless device drivers) from S3 on a UP kernel by 
doing the following at resume:

	i8259_reinit();
	lapic_enable();
	lapic_initclocks();
	ioapic_enable();
	lapic_set_lvt();

What else should I do to ensure that things are configured properly in 
the MULTIPROCESSOR case?

Cheers,
