Incidentally I just thought about this and I fixed the problem at
2.3.99-pre2 time. With classzone design if nobody is doing a GFP_DMA
allocation (and nobody is doing that because as you said you don't have
soundcard and you don't use the floppy) then _nobody_ will ever to try to
take some page free from the DMA zone. The DMA zone can be shrink of
course but it will be considered as a whole with the NORMAL zone. Or see
it in another way: when you'll do a GFP_KERNEL allocation the kernel will
behave exactly if you would have only one zone (if you have less than 1
giga of ram of course).
