unremovable files and possible fs corruption (2.1.123)

I'd just upgraded to 2.1.123 when after a few reboots fsck claimed that
the one filesystem wasn't clean. I did a 'fsck -y' and there were screens
of error messages (which I ignored). After a reboot, fsck complained again,
that the superblock was missing, so I rebooted 2.0.35 and did an 'fsck -b
8193'.

Again, pages of error messages; complaints about duplicate blocks and
multiple referenced blocks and stuff. However, now the filesystem was
fixed. There are about 8k files in lost+found.

So I scanned the kernel list to see other complaints about 2.1.123 and
filesystem corruption, but saw none, so I'll put it down to either hardware
or maybe a virus on the windoze partition.

But now for the intersting bit: at various places in the filesystem are to
be found files like:

b--xr-srwt 1 28268 25967 101, 111 Sep 9 2028 kcontrol

and in lost+found:

?-----x--x 1 root 12785 5840 Mar 10 2032 #116513
?--------- 1 root 25579 0 Jan 1 1970 #116576
?--S-wSr-- 1 52 13364 269356 Mar 11 1970 #116578
?---rwSr-- 1 108 9300 7625788 Apr 5 1970 #116579
b--x-wsr-- 1 116 25724 108, 108 Mar 30 1970 #116580
?--x-wsr-- 1 132 31852 9206876 Apr 11 1970 #116581
?-w-r-Sr-- 1 28 25804 1858740 Jan 22 1970 #116584
?---r----- 1 root 4096 0 Nov 14 1924 #116588

These files, however are un-removable:

[root@chippo lost+found]# rm -f "#116588"
rm: #116588: Operation not permitted
[root@chippo lost+found]# chmod 666 "#116588"
chmod: #116588: Operation not permitted

Can anybody suggest how I can get rid of these things?
