It might be possible (don't know why it does not work for you), but bear in mind that PCI is *very* slow compared to your main memory.
[Oh, you might want to add that memory late in boot phase. At begining of kernel boot, that area is probably not mapped, yet. PCI is initialized later.] Pavel -- (about SSSCA) "I don't say this lightly.
