I have a 1Gb primary swap partition (/dev/sda1)
and fdisk -l shows that. But the command

# swapon /dev/sda1

says that ..:/dev/sda1: is invalid argument.
I made an entry in /etc/fstab (too):
/dev/sda1 none swap sw 0 0

but swapon -a still syays that it is invalid argument!

Any pointers?

Have you "formatted" the partition with mkswap?

fdisk read the partition table from the disk, but the kernel data can be
seen in /proc/partitions (it is read at boot time)

what about

file -s /dev/sda1

?

If "grep sda1 /proc/partitions" shows the expected result, try
mkswap /dev/sda1
before
swapon /dev/sda1

Did you create a "swap filesystem" on the partition?

# mkswap /dev/sda1 && swapon -a
