I tried following this, not sure if this was mentioned before. This
/dev/hda1 was formatted as swap space originally, correct? It doesn't
happen to be the same disk as your root partition (i think that would
be impossible to do anyway).

Its either that or your C libraries are royally screwed. Is it just
this that fails, I am inclined to think that your machine shouldn't be
working at all. Were you by any chance upgrading your system and your
kernel or experimenting with your kernel.
Other possibilities are you recently or have always had incompatible
ram. I find that you should try to have the same brand of ram chips.
Mixing ram chips of different types, even from the same vendor may
cause issues. Well its mainly all these different timings on the rams
that cause conflicts. If you want to confirm it has nothing to do with
your ram, either install memtest on your system, and boot to it:
or use a live cd, any sane distro should have memtest86 as one of the
boot options on the livecd. Test out your ram, and see if it is
functioning. Go through atleast one full pass before killing it, and
dmake sure you get 0 errors.
