xfx radeon 5450 card in ubuntu

I recently bought 1GB video card of 'xfx radeon hd 5450'
It came with cd for drivers of windows.
I installed fglrx.
Still in ubuntu 10.10 (lucid) I ran
lspci -v | grep -i prefetchable
which shows 256M which is video memory of my ASUS motherboard.

What should I do ?
Attached is dmesg log.

You haven't actually explained what the problem is or what you are trying to accomplish. In your first post you say you've already installed fglrx. So what are you doing in steps 2 and 3 and why are you doing it?

Sorry for late reply.

when I run 'lspci -v | grep -i prefetchable'
I get
	Prefetchable memory behind bridge: 00000000d0000000-00000000dfffffff
	Memory at fe9ffc00 (32-bit, non-prefetchable) [size=1K]
	Memory at fe9fe000 (32-bit, non-prefetchable) [size=4K]
	Memory at fe9fd000 (32-bit, non-prefetchable) [size=4K]
	Memory at fe9ff800 (32-bit, non-prefetchable) [size=256]
	Memory at fe9fc000 (32-bit, non-prefetchable) [size=4K]
	Memory at fe9fb000 (32-bit, non-prefetchable) [size=4K]
	Memory at fe9ff400 (32-bit, non-prefetchable) [size=256]
	Memory at fe9f4000 (64-bit, non-prefetchable) [size=16K]
	Memory at fe9fa000 (32-bit, non-prefetchable) [size=4K]
	Memory at d0000000 (64-bit, prefetchable) [size=256M]Seems to be video memory on motherboard
	Memory at feae0000 (64-bit, non-prefetchable) [size=128K]
	Memory at feabc000 (64-bit, non-prefetchable) [size=16K]
	Memory at febc0000 (64-bit, non-prefetchable) [size=256K]
Does the first line suggest video card ? How can I conclude it is 1GB ?
