Bug#497791: bug reopen

[Michele Porelli]

I've just upgraded my sid and after a reboot I encountered this problem..
In order to  boot I must replace  the "search --fs-uuid" line with
"insmod linux"

I've also another problem, parameters with a space or in to quotes are
badly interpreted by grub2:
For example I've some problem with my ACPI table and I would not
recompile my kernel to patch it. To avoid this problem I can boot my
system with this parameter: acpi_os_name="Microsoft Windows NT"
However grub2 seem confused and the OS name assigned is wrong.
This problem affect also the older version of grub2.

grub-pc version: 1.96+20090628-1
grub-common-version: 1.96+20090628-1
