we (I) am working on an overhaul of the Graphics wiki currently. the 
current Graphics wiki is a bit out of date in regardsd to the whole DRM 
overhaul that's happened in the past year or so.

It will have lots of updates in regards to both i915 DRM as well as 
Radeon/AMD DRM code that has been recently updated.  I will have per GPU 
driver instructions as well (i.e. kld_list="i915kms" for intel systems, 
kld_list="radeonkms" for AMD systems).  Hopefully this will help reduce 
confusion.

Interesting, I may have missed those bug reports, in my testing I have 
not had this issue.  Is there a mailing list thread or PR I can take a 
peek at to verify this is an issue?

thanks!
