Multiboot & extended partition problem

[speedygeo]

I use different systems on my laptop to test and help purpose.
Now I have this situation:
sda1 WinXP
sda2 Kubuntu karmic
sda3 Fedora
sda4 extended
sda5 home
sda6 swap
sda7 opensuse
sda8 chakra

I installed the kubuntu grub 2 on the MB, but for all the other linuxes I installed their grubs on their partitions.
I can use without problem winxp, kubuntu and fedora. The grub recognize opensuse and arch, but can't access there.
Can anyone help me?
