i'm thinking about converting my OS (ubuntu) to the 64 bit version to use the last bit of memory (4 gb)—ok, it's rather reinstalling …
will this work as expected or are there possible limits given by the mainboard/memory controller/some other component, so i cannot fully utilize my full ram? if so, are there benefits from upgrading anyway?

*-pci
description: Host bridge
product: Mobile PM965/GM965/GL960 Memory Controller Hub
vendor: Intel Corporation
physical id: 100
bus info: pci@0000:00:00.0
version: 0c
width: 32 bits
clock: 33MHz
i'm concerned about width: 32 bits
is that because my current kernel is only 32 bit, or because my hardware can't do more than 32 bit. (that'd suck …)
edit
i found the following on dell's website about my laptop:
Dual Channel DDR2 Shared Memory
Available DIMM Slots:
Two Memory slots offering up to 4GB
so what now? all answers to this question suggest there is no hardware limit. all answers wrong, or was my question misleading?
