OK, I think the problem is that the system allocates so much highmem pages for the ramdisk that it's become impossible for kswapd to ever meet the free target.
I _think_ this has been fixed in a more recent -ac kernel, but haven't tested it with such a huge ramdisk...
If it is possible, could you test 2.4.12-ac3 ? (if it's still broken, I'll go fix it)
