Fix for radeon interlace modes

You'll be interested to know I've written a patch to fix this, by doubling the values of the vtotal/vdisplay/vsyncstart CRTC registers when in interlaced modes, the same should probably be done for CRTC2 registers.

I've just reported this via Fedora's bugzilla as my patch applies to the Fedora source after their other patches, hopefully it'll find its way upstream from there, or you can tweak the patch to apply it for other distros, I've attached it here for reference
