Help needed debugging xf86-video-siliconmotion driver

[Laércio de Sousa]

Hi there!

Some time ago I've reported a bug against xf86-video-siliconmotion driver
describing a very strange problem that affect my Silicon Motion SM501 video
card:

https://bugs.freedesktop.org/show_bug.cgi?id=79893

Teddy Weng from Silicon Motion replied me this small message:

"The new  Linux Distro has some problem in writing PCI config space. You
can enable memory IO access manually. You can check SM501 PCI config space
address 0x04,bit 1. Please let this bit to be '1'."

I have no experience in xorg video driver maintainance, nevertheless I'm
trying to study xf86-video-siliconmotion source code in order to fix that
problem. Anyone has any idea of where should I start patching the driver to
implement Teddy's solution?

Thanks in advance!
