Well, I've answered my own question regarding highmem. Reserving 256MB
ram causes high-mem mapped IO to fail. I can have penguins, but no
filesystems or no penguins and a useable system. I'm guessing that I
could probably turn off HIGHMEM and HIGHMEM-IO and might be able to get
penguins back, but at the cost of reduced system performance. I'm not a
kernel hacker, but I might just see how bad I can break vesafb to remap
only the necessary memory for the requested video mode. Perhaps that
would fix the whole thing?
