Uh, oh. Methinks I see an issue here. First, I didn't know you could
use labels for swap partitions (since they don't have a real filesystem
on them). I've always used the /dev name of the device (in my case
using LVM, it's /dev/VolGroup00/LogVol01).
On top of that, partition 4 is the extended partition which contains
/dev/hda5, /dev/hda6 and so on. Using that as swap (if you could force
it) might cause LOTS of grief. A dump of "fdisk -l" would be nice.
If you have a /dev/hda5 in there, then using hda4 as swap can be fatal.

What does "swapon -s" show? Here's mine (granted, X86_64):
[root at prophead ~]# swapon -s
Filename Type Size Used Priority
/dev/mapper/VolGroup00-LogVol01 partition 2031608 1500 -1
