Slightly less hackish implementation of that hack attached. This (on top of my max_dma_address patch before) does solve the ramdisk related atafb problems without resorting to artificial RAM limits. Stephen, please try this patch.
You can reserve a specific area using reserve_bootmem, so that you don't have to rely on alloc_bootmem_low returning memory from the correct zone, e.g. in atari_stram_reserve_pages you already have a pointer to the start of free memory. In general stram.c could use a major cleanup. It would be better if it used resources like amiga/chipram.c.

In the end it should simply use a single allocation type, if there is something that needs ST-RAM before the allocator is initialized, it either has to be delayed or special cased. bye, Roman - To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
