Description of problem:

I have a 

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility HD 3670

and I've noticed in Xorg.0.log that it's only using half the vidoe memory that the system has:

(II) RADEONHD(0): The detected amount of videoram exceeds the PCI BAR aperture.
(II) RADEONHD(0): Using only 262144kB of the total 524288kB.
(--) RADEONHD(0): VideoRAM: 262144 kByte

It would be nice if it used it all ;-]

Version-Release number of selected component (if applicable):

$ rpm -qa | grep radeon

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command

yum upgrade --enablerepo='*-updates-testing'

Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

Xorg.0.log for f12

It's not listed the same way, but it appears that it's still only using half the available memory.

(II) RADEON(0): [DRI2] Setup complete
(II) RADEON(0): Front buffer size: 8704K
(II) RADEON(0): Remaining VRAM size (used for pixmaps): 249312K

However, could this be that it's reserving the other half for the other display?  ie it's a laptop with and external monitor connection, so it the other half being reserved incase I plug a external monitor in?

I haven't got the laptop anymore, so I can't really test this!  Since it's was only I that noticed, it makes sense to let i drop
