"drm" and "i915" kernel modules successfully built for sparcv9, but a 
number of unresolved symbols.
Should not be too difficult to fix.

Note: "drm" is the general device-independant part. "i915" is the 
device-specific one. One would have them in [...]/kernel/drv/'isainfo 
-k'/i915 and [...]/kernel/misc/'isainfo -k'/drm.
"drm" is a submodule that gets pre-loaded by the device-specific 
modules, currently limited to i915 on Solaris. But the framework should 
be rather easily extensible to cover the other chipsets already 
supported on linux and bsd.

Maybe soon ...

p.s. Sorry for cross-posting. But at least I, as a SPARC user, find this 
important enough. Further: It actually also covers enhancing DRI support 
to the missing chipsets on x64/x86, because the framework of the ported 
i915 can easily be cloned for the other devices.
