I also got quite a few "Couldn't get a free page" messages while testing the Olicom Token-Ring driver currently being developed, especially if I was beating the disk hard at the same time - e.g. unpacking kernel sources and such. This was on a 20 MB 486 w/ ISA bus only.
(The driver uses DMA for data transfer, so it needs 4 KB buffers below 16 MB for the ISA cards - that appears to trigger it)
I tried the old echo "128 256 1024" >/proc/sys/vm/freepages and haven't seen it since.
