The reason agp_generic_create_gatt_table() fails is that
ioremap_nocache() always return NULL. (Whether or not the subsequent X
crash has anything to do with this is not clear -- the ATI wrapper has
quite a few references to virt_to_phys(), so likely some problems there
as well.)
Is there a good reason for this / what will it take to implement
ioremap_nocache correctly?
Jacob
