This is _very_ _good_ news indeed.
Thank you (personally).
This shall help us in making
ati (plus related sub-modules incl r128 and radeon), /* PGX8,
PGX24, PGX64, XVR-50, XVR-100 */
radeonhd as well as ...
/* XVR-50, XVR-100, XVR-300 */
mga,
/* XVR-200 */
glint
/* PGX-32 aka Techsource Raptor 8p */
work without facing the known SPARC-libpciaccess problems.
Plus it removes the need to depend on the insecure aperture driver, if
we can get it working by then having ast as reference/template plus
reverse-engineering.

Ok, understood.

I'm 100% exited about ast going into the fox-gate, really looking
forward to it :))
