Any chance Benjamin could also test it? The behaviour is different
from 2.6.24-rc1 since we call atp_geyser_init for all geysers now.

I was hoping that FOUNTAIN_TP_ONLY_PRODUCT_ID (0x30A) behaves similar
to Geyser in this regard. If you know that this assumption is incorrect
then we need to rename atp_is_older_fountain() to atp_is_fountain()
anf add this product ID to it.
