We haven't made a dump of the entire partition but the system
has no activity and we're looking directly in /dev/sda2 while
in runlevel 3 (RH 5.1 + numerous updates).

I recall about 20 corrupt inodes (estimated guess from what I saw
in /lost+found -- this has all been cleared by debugfs) and two
remaining ones which still do exist because fsck doesn't consider
them unusual (even e2fsprogs-1.15-0 doesn't). See another
posting for more info about the second corruption case.
