[Wine] Page fault in xinerama_init

[lewisd at gmail.com]

Trying to run any program in wine (even a program that doesn't exist,
like notepad.exe) gives a page fault error.  I think this is because
I'm running dual head, and may have something to do with my video
card, which is a ATI FireGL V3100.

Here's the debug output:
$ winedbg notepad.exe
Invoking /usr/lib/wine/wine.bin winedbg.exe notepad.exe ...
WineDbg starting on pid 000a
First chance exception: page fault on read access to 0xffffffff in 32-
bit code (0x7e6a7169).

I really don't know where to procede from here.
