4 All the comments about enabling 4G highmem are correct - the kernel can't
5 address a full gig without it. However, enabling this slightly slows
6 down your memory, and some people choose to keep it off for speed unless
7 they're using the full gig. Another option, better imho, is to use a
8 kernel with the 1g_lowmem patch (originally from -ck patchset) or to
9 patch it in yourself, which enables exactly 1 gig of memory at full
10 speed.

12 The patch for kernel 2.6.12 is available here:

14 If you need it for a different kernel version, start here:
