It doesn't fix it, swapped memory and cache memory increase at a
rate of about 40K/s, swapping process very fast, even the "agetty"
processes get 64 out of 68 K swapped one or two minutes after booting.
This rate gets lower as nothing but the essential (4K of "agetty", etc) is
left in the physical memory.

I'll test this later as I cannot reboot the machine right now.
Just one question, is this kernel 'stable', I was running 2.4.5-ac9 for
a week without problems, even when 'stress-testing' the emu10k1 and the
mga modules.

PS: swapoff -a fixes the problem :-)
