Actually, I think they aren't, that's why they're not ARGB as well. This
isn't a feature of KDE but the new Xlib.
The problem has been discussed on the XFree86 lists; the radeon 2D
driver function to wait for a vertical blank interfered with the DRM
handling vertical blank interrupts. This has been fixed in XFree86 CVS
after RC1. DRI CVS doesn't even have the affected code yet.

'Of course'? A crash is a bug. Does this patch help?
