It is my understanding that yes, you can use 11g grid+ASM with a 10g RAC database.
Install 11.2.0.2 Grid Infrastructure which includes the cluster stack
AND ASM. As stated earlier, the Cluster stack (formerly CRS) and ASM
are combined into one.
Install 10gRAC (preferably 10.2.0.5) database software
Create and move the database.
