When installing ubuntu 9.10 karmic koala will grub2 work together with grub legacy

[bqz69]

grub2 seems to work ok, but it needs some editing, to show all partitions in 
the bootloader menu.

I just tried to reinstall 9.10 on sda8 to test once more how grub2 worked.

I have the following partition setup:
sda1		windows xp

sda2		8.04 with grub legacy

sda5		9.10 /boot		
sda6		9.10 /  	encrypted
(9.10 are using grub2 as per default)

sda7		debian 5.03	grub legacy

sda8		Here I installed 9.10 (with grub2)

After installation on sda8, grub2 Found: sda1, sda2 and sda7 - it did not find 
sda5.

Then I logged into sda8, and copied the menuentry group FROM 
/boot/grub/grub.cfg on sda5 TO /etc/grub.d/40_custom on sda8 and then I ran 
"sudo update-grub"

When I did this, all partitions was shown to be found except sda5

Then I booted again, and now the grub2 bootloader menu showed all partitions 
as expected.

I am using ext3 on all my ubuntu OS.

I find it a bit strange, that grub2 find the 2 OS with grub legacy but not the 
one with grub2

Here is shown the menuentry group i copied from sda5 to sda8 (it is just an 
example):

menuentry "Ubuntu, Linux 2.6.31-14-generic" {
        recordfail=1
        if [ -n ${have_grubenv} ]; then save_env recordfail; fi
	set quiet=1
	insmod ext2
	set root=(hd0,5)
	search --no-floppy --fs-uuid --set 6e57c9a2-6d40-4c16-a15f-3972c66ed134
	linux	/boot/vmlinuz-2.6.31-14-generic root=UUID=6e57c9a2-6d40-4c16-
a15f-3972c66ed134 ro   quiet splash
	initrd	/boot/initrd.img-2.6.31-14-generic
