20 That's only necessary for 32-bit kernels. If your Processor family is
21 set to AMD-Opteron/Athlon64 (CONFIG_MK8), which I think is a fairly safe
22 assumption on this list, then you automatically get support for well
23 over 4GiB of memory (I can't remember exactly how much is supported, but
24 it's much, much more than 4GiB), and without the performance tradeoff of
25 the 32-bit HIGHMEM support.
26
27 I've got 2 * 1GiB sticks in my box right now. Works wonderfully.

29 Good luck,
