wine users - Dec 2010 - Hybrid graphics, Wine with Bethesda games

I just bought a new laptop and decided to go for Linux. I'm getting to know
the Terminal slowly, but I'd like to run Oblivion and Fallout 3. The specs
are sufficient. The problem with these games (I haven't tried others with
Wine yet) is that they don't seem to recognize the other graphics card in
there, in addition to the Intel chipset, and that is Radeon HD 5700. In fact
I'm not sure Ubuntu knows about it at all, and it's hard to check when
you can't run the games!

Here is what I know:


Code:
lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor
Integrated Graphics Controller [8086:0046] (rev 02)
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Manhattan
[Mobility Radeon HD 5000 Series] [1002:68e0]



Seems to be here, but under Wine the Options of Fallout and Oblivion show the
Intel chipset as the graphics card in use. Which may be true, I don't know
how to see which card is active or switch to it. There was a program I
downloaded, gone now, that let me force-switch to the Radeon, but then Options
of Oblivion saw NVidia 7900 instead!

How to have Ubuntu and the games see my good card is question 1. Now running the
games is not really possible either: with Oblivion (chipset for graphics) the
intro movie crawled by so slowly, stuttering and devouring processor speed, that
I never finished waiting for the menu to appear, and even shutting down the
virtual desktop was not so easy. With Fallout 3 I got to the menu at good speed,
although the LIVE button there only halted the animation, but when I tried to
actually start a game, it crashed. And again getting out of the desktop is a
hassle.

Ubuntu gurus out there, help.

One thing that may have to do with this is that I have no Direct 3D folder in
the registry under HKEY_CURRENT_USER / Software / Wine at all. Wine is version
1.2, just installed it's hard to say why it would be damaged.
