Grub problem and swap partition

[edie]

I have installed VectorLinux on a system on which I already have
WindowsXP and LinuxMint. LinuxMint installed GRUB as bootloader.
During the installation of Vector I have not installed LILO.
Here is the partition table of my HD
Device Boot Start End Blocks Id System
/dev/sda1 * 1 69759 35158221 7 HPFS/NTFS
/dev/sda2 222946 232575 4853520 12 Diagnostica Compaq
/dev/sda3 69759 222945 77206027+ 5 Esteso
/dev/sda5 69759 89139 9767488+ 83 Linux
/dev/sda6 89139 96885 3903763+ 82 Linux swap / Solaris
/dev/sda7 96885 135645 19535008+ 83 Linux
/dev/sda8 135645 174405 19535008+ 83 Linux
/dev/sda9 174405 182155 3905968+ 82 Linux swap / Solaris
/dev/sda10 182155 193781 5859472+ 83 Linux
/dev/sda11 193781 222945 14699097 83 Linux

/dev/sda9 is the swap partition of Vector
/dev/sda10 is the root partition of Vector (xfs filesystem)
/dev/sda11 is the home partition of Vector (xfs filesystem)

I have tried many modifications in the /boot/grub/menu.lst file of the
Mint installation in order to add Vector but I have not been able to make it works.
The last try was as follows

title VectorLinux
root (hd0,4)
kernel (hd0,9) /boot/vmlinuz-2.6.25.7 root=/dev/sda10
initrd (hd0,9) /boot/initrd
quiet

Another question: is it possible to use the same swap partition for
Mint and Vector ?
Thanks in advance.

You only need one swap partition - to my knowledge you never run two distros at the same time
Why this?

root (hd0,4)
kernel (hd0,9)

Should be root (hd0,9)
I have never managed to install Vector, got some hardware problems and gave up
