Is there any obvious reasons why this isn't compiling?

Try compiling with SiS framebuffer device (CONFIG_FB_SIS and CONFIG_FB_SIS_300 or CONFIG_FB_SIS_315) activated... the SiS DRI driver needs it... don't ask me why ;)

Because they share common code. It is actually better that they work together since this way they will not step on each others toes. Someday I plan to merge both the fbdev and drm interfaces together.

More precisely, the framebuffer driver contains all the chipset and therefore the memory (amount/type) detection stuff. It checks for eventual Turbo/Commandqueue capabilities (which differ significantly depending on the actual chipset used) and sets up a memory heap taking all the hardware specifics into account. Moving the memory management to the DRM module will result in a lot of duplicate code and a lack of common memory management.

If you don't want to use the framebuffer, start it with no video mode specified or with mode=none (or mode:none if as kernel parameter)
