Well, setting remote=0 does have an effect (af9015.c):
if (val == AF9015_IR_MODE_DISABLED || val == 0x04) {
af9015_properties[i].rc_key_map = NULL;
af9015_properties[i].rc_key_map_size = 0;
While every other (valid) value for "remote" assigns a key map at that point
and further sets the af9015_config.ir_table. I guess thats has consequences
so that even if polling occurrs, it doesn't cause a whole lot of other
actions.

Where "proper" would be? :-)

My guess would be that each polling action generates several USB packets
which in turn cause several wakeups...

Does your vdr let your machine sleep nicely?
