Yes, I did. I think that the problem was that I didn't
reboot the system after creating the partitions. I did:
# mkfs.ext3 -cv /dev/hdb5
immediately after creating the partitions. Only after
writing the bug report I found in the manual that it's
recommended to reboot the system.

Thanks for the explanation! I think that what happened was
what you described: there were only file names, not files at
hdb5. But no problem: I had a backup in another partition
(hdb7). So, I didn't lost any data.
I used parted to delete the two new partitions and create
them again. Then I restored the data from the other
partition. This time I rebooted the system about two or
three times between operations. The 32 bit programs that are
in this partitions are running normally and the result of
"df" command is meaningful:
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hdb1 6728280 3403348 2983152 54% /

tmpfs 511380 0 511380 0% /dev/shm
However, the partition got a different number (it's now
hdb8) and cfdisk reports a problem:
# cfdisk /dev/hdb
FATAL ERROR: Bad logical partition 8: enlarged logical
partitions overlap
Press any key to exit cfdisk
There is no error, according to parted:
root@:~# parted /dev/hdb print

Information: Don't forget to update /etc/fstab, if necessary.
On the one hand, probably the problem was caused by a wrong
usage of cfdisk. Then, this bug could be changed to
wishlist: "More clear warning that the system must be
rebooted". Something like a blank screen with only the
message: "ERROR: The kernel failed to read the new partition
table. You must reboot your system!". This might not be
necessary for experienced Unix users, but Linux is receiving
many people migrating from other OS.
On the other hand, it's strange that parted and cfdisk
disagree about how healthy are the partitions.
Thank you for your reply,
Best regards,
