that just means it probably doesn't have bad ram, but it doesn't mean
you didn't get an ecc error (memory errors are statistically possible
even with the best ram, cheap ram is just more likely than expensive
ram usually)

reiserfs is also sensitive to marginal ram --- this is relative to
ext2 which is much less sensitive it seems
don't know about ext3 or jfs

no, usually it doesn't even notice, things just silently go bad
if the kernel can detect it it usually panics as it doesn't presently
have the infrustructure to deal with things. fwiw there are no ECC
drivers in mainline anyhow for the most part if we are talking ia32,
for other platforms (ie. ia64) you get events and the kernel will
usually just panic
