[Bug 1098] New: - DGA2 error

http://bugs.winehq.com/show_bug.cgi?id=1098

Summary: DGA2 error
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When running a game (Neverwinter Nights or even NIVDIA's (windows) Treemark)
with the following options:
--debugmsg +x11drv
I get the following line error:
warn:x11drv:X11DRV_XF86DGA2_Init disabling XF86DGA2 (insufficient permissions?)

I have set all permissions to /dev/mem completely open and added myself to the
"mem" user group (and set back the original rights to /dev/mem, when doing the
latter).
So there should be sufficient permissions.

Searching in the internet gave only one other reference
(http://cwrulug.cwru.edu/pipermail/sigunix/2002-August/001065.html) to this
problem, but there was no answer to the problem. I emailed that person but I
didn't recieve a reply yet.
So I hope somebody here can solve this bug.

I took the following steps to install all things needed:

I use Mandrake 9.0 with XFree86 4.2.1 .
I have installed all Mesa-packages. After that I installed NVIDIA's 1.0-3123
drivers for my Geforce2 MX400 and made changes in XF86Config-4.
I enabled Alsa.
And I simply compiled Wine20021007 (downloaded tarball from
http://source.winehq.org/source/ANNOUNCE).
