debian 6.0.7 amd64 raid0 lvm crypt - bootloader issue

[<shmick@riseup.net>]

Hi all,

Having installed debian onto a hardware raid pc setup, using dmraid=true
switch, I attempt to repair the failed grub/lilo bootlader install after
rebooting into rescue, again with dmraid=true

How can I get grub installed?  

Background info:

Partitioning setup according to guided lvm crypt defaults with all installed
onto same partition

Using this setup /boot was created as primary partition under raid stripe
Ie /dev/mapper/long-sata-raid-name1

All else is located in logical encrypted volume
Ie /dev/mapper/long-sata-raid-name5

Start rescue mode and select /dev/my-volume-group/root to start shell

>update-grub
->/usr/sbin/grub-probe: error: no such disk

	Do I need to edit /boot/grub/device.map and if so what should I add
?

	Current device.map includes

(hd0) /dev/disk/by-id/1st-sata-disk
(hd1) /dev/disk/by-id/2nd-sata-disk
(hd2) /dev/mapper/long-sata-raid-name

>grub-install /dev/mapper/long-sata-raid-name
->/usr/sbin/grub-probe: error: no such disk

?
