Yes, of course, sorry for not being more explicit. :) > Well, extremely low is a bit of an exaggeration. On 32 bit x86, lowmem > is 896MB. This is only 128MB higher than on your machine, or 16.7% more. My surprise wasn't the HIGHMEM split itself, but the fact that it's needed at all. I have x86(-32) machines with over 3 GiB of usable RAM which don't need HIGHMEM support.
