So your swap is supposed to be /dev/hda5.  Please do

# mkswap /dev/hda5

[BTW, you could create the swap as a primary partition too.]

Please add the following line to your /etc/fstab:

/dev/hda5	swap	swap	defaults	0 0

Then (assuming you have run mkswap already) please do

# swapon -a

and check if it shows up in /proc/swaps .
