ASM Buffer Cache - which parameter is responsible for this?

Question

Env: Oracle 10.2.0.4.0 on Windows 2003 R2 32 bit
In one of my testing databases, I saw this. Rest all databases (development and testing) do not have the component "ASM Buffer Cache".
SQL> select component, current_size, user_specified_size from v$sga_dynamic_components;
COMPONENT                          CURRENT_SIZE USER_SPECIFIED_SIZE
shared pool                         553,648,128         209,715,200
large pool                            4,194,304                   0
java pool                             4,194,304                   0
streams pool                                  0                   0
DEFAULT buffer cache                360,710,144         314,572,800
KEEP buffer cache                             0                   0
RECYCLE buffer cache                          0                   0
DEFAULT 2K buffer cache                       0                   0
DEFAULT 4K buffer cache                       0                   0
DEFAULT 8K buffer cache                       0                   0
DEFAULT 16K buffer cache                      0                   0
DEFAULT 32K buffer cache                      0                   0
ASM Buffer Cache                              0         314,572,800I am not able to figure out from the component "ASM Buffer Cache" is coming in this list. Current_size is zero so its not of a concern actually but I was wondering which parameter enforces this value.
Can anybody shed some light on this?

Forgot to mention that we are not using ASM at all.

I have some databases running on 10.2.0.3.0 (testing + dev) and others on 10.2.0.4.0 (dev databases) and I can see this component in all of them.
I have no databases running at earlier versions of 10g so cannot confirm if it was there earlier too.
With your hint of 11g in mind, I searched 11g documentation too and could not find any references to this component.
